[OS X TeX] questions: xy-pic

[Richard Seguin]

I've downloaded both xy35mac and xy-3.7. Is there any particular reason 
that I should be looking at xy35mac despite the earlier version number?

The second question betrays my lack of detailed knowledge of the UNIX 
underpinnings of OS X. The installation instructions mention 
installation on UNIX by using the command ./support/install-tds <texmf> 
or the command  make TEXMF=<texmf> install. I am inclined to doubt that 
this works on OS X. Am I correct?

All this because AMS LaTeX can not create simple triangular commutative 
diagrams, a glaring limitation. I hope that in the future this 
capability is part of the standard distribution.
