this is because Xaw3d uses imake.

In /usr/openwin/lib/config you'll need to edit site.def and uncomment out
these sections:

#ifndef HasGcc2
#define HasGcc2 YES
#endif

#ifndef HasCplusplus
#define HasCplusplus YES
#endif 

I ended up also editing sun.cf and adding 
#if HasGcc || HasGcc2
#define PositionIndependentCFlags -fPIC -DPIC
#endif
#if HasGcc || HasGcc2
#define PositionIndependentCplusplusFlags -fPIC -DPIC
#endif

right near where the tests for SunC are.  Search for -Kpic and you'll
find it.

I wonder if perhaps our bootstrap kit should set these things based
on if PKGSRC_COMPILER=        gcc

or not.

ah.  I'd had this problem too!  Didn't figure out why yet.  Could be
some more imake fallout.
