[Gnash] Setting the qt lib dir in Gnash CVS fails in Gentoo.

[Harley Peters]

In Gnash cvs setting the qt lib dir with --with-qt-lib fails with the 
following error:

ls: cannot access /lib/libqt*-mt.*: No such file or directory
configure: error: /usr/qt/3 directory doesn't contain qt libraries.

This is caused by the fact that in Gentoo the /usr/qt/3 directory has 
both a lib64 directory and a symlink called lib linked to lib64.
If i remove the symlink and move lib64 to lib Gnash works as expected.
However that of course breaks other things.

I need to set the qt lib dir because the default detection method seems 
to be too generic and compiling fails on systems that have both qt3 and 
qt4 installed. error listed below:
