It looks like my random ideas are not good.

However, in the meantime, do you think it would be OK to remove the 
"broken" status of the port science/libctl?  It does build just fine 
under i386 FreeBSD-8.2-stable.

Or maybe a better idea is to rewrite the BROKEN message:

BROKEN=	Does not build with some versions of FreeBSD with i386 or 
sparc64.  But try make -DTRYBROKEN to see if it works for you.
