Coming late to this thread: even when the CM-Super fonts are  
installed, files are generated inside /private/var/tmp/texfonts/.  
This is because LaTeX needs certain TFM files, either because the  
document you're typesetting uses them, or because these are required  
when compiling the LaTeX format. And the only way to create them is  
to run METAFont on the appropriate .mf source files.

For example, on a new Mac I've just got and on which I've only  
installed gwTeX without typesetting any (La)TeX document yet, there's  
already:

This is because the TFM file ecrm1000.tfm is required when creating  
the LaTeX format at the end of the Configure stage of the TeX i- 
Package. It corresponds to the EC font ecrm1000 (an 8-bit extension  
of the original crm10). And, as Peter Dyballa pointed out, Jorg  
Knappen is the author of the EC fonts (hence jknappen), and METAFont  
is by default configured to generate bitmap fonts for the LaserJet 4  
printer (hence ljfour) which has 600 dpi resolution (hence .600pk).

Here:

- ecrm1000.mf is a generated METAFont source file, calling files in  
turn from /usr/local/teTeX/share/texmf.tetex/fonts/source/jknappen/ec/.

- ecrm1000.tfm is the generated metrics in TFM format.

- ecrm1000.600pk is the generated bitmap font in PK format at 600 dpi  
resolution.

In case you don't need generation of bitmap EC fonts (for example  
you've installed the CM-Super fonts, or you're always using  
PostScript fonts such as Times etc. when you write \usepackage[T1] 
{fontenc}), then there's an easy way of avoiding the generation of  
the EC TFM files inside /private/etc/tmp/texfonts: install, in /usr/ 
local/teTeX/share/texmf.local/fonts/tfm/jknappen, all the files from  
the tfm subdirectory of <ftp://tug.ctan.org/pub/tex-archive/fonts/ 
ec.zip>. In this way you'll get all the EC TFM metrics pre-installed.

Hope this helps,
