I decided to add
CXXFLAGS=  -Wl,-R/usr/gcc/lib
to mk.conf. Gmp's configure script bails out:

checking C++ compiler g++  -mcpu=ultrasparc -mtune=v9 -O2 -pipe 
-Wl,-R/usr/gcc/lib... no, program does not run
configure: error: C++ compiler not available, see config.log for details


From config.log:

CXXFLAGS chosen by autoconf: -mcpu=ultrasparc -mtune=v9 -O2 -pipe 
-Wl,-R/usr/gcc/lib
configure:10051: checking C++ compiler g++  -mcpu=ultrasparc -mtune=v9 -O2 
-pipe -Wl,-R/usr/gcc/lib
Test compile:

failed program was:

int main (void) { return 0; }


I can compile and run this program by hand with the above g++ command. Somehow, 
pkgsrc is adding a lot of variables to my environment breaking my intention. 
Bmake PKG_DEBUG_LEVEL=1 configure shows:

I don't know where it breaks.

Spock:  Captain, it doesn't appear in the symbol table.
Kirk:   Then it's of external origin?
Spock:  Affirmative.
