mrtex2im is nice except it has some hard-coded paths (/usr/bin for  
latex, dvips and convert).

1. I can put in symlinks, e.g., /usr/bin/latex -> /usr/texbin/latex

2. I can edit mrtex2im.ss in a test area.

I tried #2 with this hackage in ~/.mzschemerc:

(let ((c (getenv "PLTCOLLECTS")))
   (putenv "PLTCOLLECTS"
           (string-append "/Users/gknauth/test/plt/collects/"
                          (if (string=? "3.99" (substring (version) 0  
4))
                              "4"
                              "3")
                          (if c (string-append ":" c) ""))))

but that didn't do anything useful.  (I use both v372 and v3.99.)

3. I can edit mrtex2im.ss where planet put it:

(build-path (find-system-path 'addon-dir) (version) "collects")
=> #<path:/Users/gknauth/Library/PLT Scheme/3.99.0.12/collects>

except then does it rebuild the .zo files automatically?

-----
The /usr/texbin path comes from the new TeX Live distribution since  
teTeX support is discontinued.

For now I've opted for #1.
