    taglib had the same problem, as do a few other ports.  I've found
that when the above error appears, the port will often build just fine
with lang/gcc34.  Thus far, I have had no problems mixing and matching
C++ ports built with lang/gcc33 and with lang/gcc34, but there's
always the possibility that there will be a link-time error or a
random crash.

    portupgrade -M "CC=/path/to/C/compiler CXX=/path/to/C++/compiler"

is your friend.
