Well, that's not an easy one to debug, unless you've got some 
experience with LaTeX already! LaTeX's error message are often 
unhelpful, as they point to a line where the error becomes blatant, 
even if the error was actually created by another instruction several 
lines earlier.

I think the most likely cause for what you experienced is that you 
compiled in pdfTeX mode a document that included the line:




or has a [dvips] option somewhere (or an option corresponding to 
another driver than [pdftex], like [textures], [truetex] or [vtex]).

How to debug this: I used BBEdit to do a multifile search for 
"c at lor@to at ps" over the whole directory 
/Library/teTeX/share/texmf.tetex/tex/latex/, it returned the name of 
several files inside 
/Library/teTeX/share/texmf.tetex/tex/latex/graphics/, including in 
particular dvips.def, textures.def, etc.

It may also be that your document uses the changebar package, and that 
this package uses the option [dvips] by default. Or that it uses the 
pstricks package, since searching for "psset at bordercolor" returns only 
the file /Library/teTeX/share/texmf.tetex/tex/latex/graphics/pstcol.sty 
which is said to provide "PSTricks color colompatibility".

How to solve the problem: replace the [dvips] option by [pdftex], or 
simply erases it (I think TeXShop has a way of figuring out by itself 
which option to use), or typeset in TeX + Ghostscript mode instead of 
pdfTeX. In case your document uses the pstricks package, then the TeX + 
GhostScript mode is the only solution.

Generally if the error message mentions a command with "ps" in its 
name, it's reasonable to try the TeX + Ghostscript mode and see whether 
it cures things.

Unless you use Fink for other purposes, you can simply throw away the 
/sw/ directory. But there's also something trickier to do, which goes 
beyond my competence: Fink modifies the default path used by the 
system, by placing, in this path, its directories for executables 
/sw/bin/ and /sw/sbin/ before those where the system executables live, 
i.e. /bin, /sbin, /usr/bin and /usr/sbin. You can see all these 
directories, for example, by opening Terminal and typing:

cd /
ls -l

which will show what's really on your disk.

So there is somewhere a file where Fink stores this path setting, I 
don't know which one it is as I don't use Fink myself. For TeX, 
specific settings are placed by i-Installer inside 
/private/etc/csh.login, maybe Fink uses this file too or some other 
file. *Beware*: if that's indeed this file, do not attempt to modify it 
unless you're absolutely positively sure of what's you're doing; making 
an error at this stage may render you Mac completely unusable and force 
you to reinstall everything (OS, TeX, really everything). As the path 
says, these are really "private" OS directories (which is probably why 
Apple hides them so carefully in the Finder).

So what's needed at this stage from somebody more knowledgeable than me 

- in which file Fink stores its path settings;

- what to do to change these settings back to their original OS X
