gcc34 build error on Freebsd 5.1

[Darryl Hoar]

Greetings,
I have 5.1 running on my machine.  I installed cvsup
and upgraded my ports with it.  I then went into
/usr/ports/databases/firebird-client and did a make install.

Of course it installed several other dependencies when
I did that.  One thing is was trying to build/install was
gcc34.  The following error was generated and the
entire process came to a halt.

../.././..//gcc-3.4-20050719/libiberty/fibheap.c:395: warning: implicit
declaration of function `memset'
gmake[2]: *** [fibheap.o] Error 1
gmake[2]: Leaving directory
`/usr/ports/lang/gcc34/work/build/i386-portbld-freebsd5.1/libiberty'
gmake[1]: *** [all-target-libiberty] Error 2
gmake[1]: Leaving directory `/usr/ports/lang/gcc34/work/build'
gmake: *** [bootstrap-lean] Error 2
*** Error code 2

Stop in /usr/ports/lang/gcc34.
*** Error code 1

I google'd and searched the freebsd website/mailing list,
FAQ, but didn't find an answer to this problem.

Anybody have an pointers/help so I can get on with the install ?

thanks in advance,

Darryl
