after applying your diffs:

setenv CC gcc42
setenv CXX g++42
setenv F77 gfortran42

setenv CFLAGS "-fPIC"
setenv CXXFLAGS "-fPIC"
setenv CPPFLAGS "-I/usr/local/include -I/usr/local/include/UMFPACK 
-I/usr/local/include/metis"
setenv LDFLAGS "-L/usr/local/lib -lmetis -lm "

./configure  \
 --enable-dl --enable-shared --enable-lite-kernel

Still get barf on sed

configure: creating ./config.status
config.status: creating Makefile
sed: 3: ./confJtlciY/subs-1.sed: filename expected

I'll look more later...

I can't speak for all *bsd; I'll try an experiment later;

I'm running a recent freeBSD stable:

and compile with a recent gcc:
