This implies that FreeType isn't installed correctly.

The directory in which ft2build.h resides should also contain a
subdirectory called "freetype". In turn, that subdirectory should
contain several freetype headers, plus subdirectories called "cache",
"config" and "internal":

  $ ls -R /usr/X11R6/include/freetype2
  freetype/  ft2build.h
  cache/      ftcache.h   ftlist.h    ftnames.h   ftsynth.h   t1tables.h
  config/     fterrors.h  ftmac.h     ftoutln.h   ftsystem.h  ttnameid.h

Yes. You can use --without-blas and --without-lapack with no loss of
functionality. --without-freetype only disables d.text.freetype, and
--without-motif only disables xganim.

What about headers (gdal.h, cpl_*.h)? Although, it appears that
r.in.gdal will compile without them when not using --with-gdal.

At present, r.in.gdal is always included in the build. --with-gdal
simply tries to link it to libgdal at build time. Without this switch,
r.in.gdal will attempt to load it via dlopen(). This will probably
fail on MacOSX; the code expects the library to have one of the
following names:


If you need r.in.gdal, I'd suggest editing the file src/CMD/head/head
after running "configure" but before running "make". But, AFAICT, this
approach requires the GDAL headers to be installed.
