the system is:

$ uic -v
Qt User Interface Compiler version 4.3.3
$ moc -v
Qt Meta Object Compiler version 59 (Qt 4.3.3)
$ g++ -v
Using built-in specs.
Target: i686-apple-darwin9
Configured 
with: /var/tmp/gcc/gcc-5465~16/src/configure --disable-checking -enable-werror --prefix=/usr --mandir=/share/man --enable-languages=c,objc,c++,obj-c++ --program-transform-name=/^[cg]
[^.-]*$/s/$/-4.0/ --with-gxx-include-dir=/include/c++/4.0.0 --with-slibdir=/usr/lib --build=i686-apple-darwin9 --with-arch=apple --with-tune=generic --host=i686-apple-darwin9 --target=i686-apple-darwin9
Thread model: posix
gcc version 4.0.1 (Apple Inc. build 5465)



and the error is in the plugin (or whatever plugin)
