Problem installling GraphicsMagick

[Liam Groener]

When I try to install GraphicsMagick (Mac OSX 10.7, MacPorts 2.0) a get a failure, apparently during linking. The error message from the log file follows:

:info:build Undefined symbols for architecture x86_64:
:info:build   "___builtin_object_size", referenced from:

:info:build make: *** [all] Error 2

Any clue on what I should do?
