[plt-scheme] compile-time error for mzscheme plt from svn / Solaris 10

Hi everyone,


Has anyone else run into a compile-time error while building mzscheme from
svn trunk?  I'm seeing the following on my Solaris box while compiling the
software:

######
gmake[3]: Leaving directory `/export/home/dyoo/local/plt/src/mzscheme'
gmake[2]: Leaving directory `/export/home/dyoo/local/plt/src/mzscheme'
gmake mzscheme
gmake[2]: Entering directory `/export/home/dyoo/local/plt/src/mzscheme'

-lintl

ld: fatal: Symbol referencing errors. No output written to mzscheme

Manually kluding in '-lresolv' to the Makefile appears to fix the problem
for me, but I'm not familiar enough with the build system to know exactly
what the proper fix is.  Thanks!
