I think that I've found the problem; configure.in uses:
This results in the check:
configure:5068: gcc -o conftest -g -O2 -I/usr/local/include -L/usr/local/lib -lgd conftest.c 1>&5
Note that "-lgd" comes before "conftest.c"; this won't work for static
libraries. I'll commit a fix shortly (basically, use multiple
AC_CHECK_LIB tests instead of AC_CHECK_FUNCS).
That may not be enough for Solaris:
ld: warning: file libucb.so.1: required by /usr/local/lib/libpng.so, not found
Let me know whether the updated version works for Solaris.

All of XEXTRALIBS, PQLIBPATH and PQLIB should be removed from the
definition of LIBES and moved to the compilation command(s), as is the
case for MATHLIB and XDRLIB.
In general, external libraries should *never* appear in the dependency
list, either directly or indirectly (e.g. via LIBES), as they will be
of the form "-lfoo".
The only libraries which should appear as dependencies are those which
are part of GRASS itself (e.g. from src/libes), as they will be actual
pathnames (e.g. "$(LIBDIR)/$(LIBARCH)/libgis.a").
