Compiz problem - Undefined symbol "animGetI"

[AN]

Clang is default compiler.
I just built a new system on current with Xorg and Gnome2, and am having a 
problem with Compiz.  The port installed successfully, but it crashes 
almost immediately after starting, and is totally reproducible every time.

I believe this is related to the switch to clang because the same hardware 
was configured the same way previously, the only difference is that the 
system where Compiz was working was compiled with GCC 4.2.

When I run the following on the command line:

compiz --replace --sm-disable --ignore-desktop-hints ccp &
gtk-window-decorator --replace &

I get:

/usr/local/lib/compiz/libanimation.so Undefined symbol "animGetI"

Should I file a PR on this? Any help is appreciated.
