[plt-scheme] build error with svn 14677

[Doug Orleans]

I did svn update to revision 14677, ran ./configure, then make aborted
with this error:

make[5]: Entering directory `/usr/local/plt/src/mred/gc2'
make[5]: *** No rule to make target `../../mred/wxme/wx_media.h',
needed by `xsrc/wxscheme.cc'.  Stop.

The directory src/mred/wxme is empty except for a Makefile.

Any clues?  I'm on Ubuntu 9.04.
