Does it contain cmr10.pl and cmmi10.pl?  Probably not, I guess.

(Alan's fontinst-1.335 came with a directory full of .pl files for
standard fonts, but I omitted that because they can be generated
whenever you need them.)

Actually, fontinst does the following:

      \get_file_name #1~scaled~1000~;

- it first looks if a cmr10.mtx already exists, and if so, it uses
  that file 

- if not, it looks a .pl file cmr10.pl and runs \pltomtx on the file,
  creating a cmr10.mtx

- otherwise, it looks for an .afm file cmr10.afm and runs \afmtomtx 
  on that file, creating cmr10.mtx

- finally, it tries to load cmr10.mtx again, assuming that it has been
  created in one of the preceedings steps

Conclusion: If you have neither a .pl file nor an .afm for the file
you requested, fontinst will trigger a low-level error when trying to
load an .mtx file.  If you want to do something fancy using CM fonts,
you have to make sure to generate the required .pl files with tftopl.
