 When I tried to install kdegraphics4 the building of qca failed:


 {{{

 So I went to the build directory

 /opt/local/var/macports/sources/rsync.macports.org/release/ports/devel/qca/work/qca-2.0.0/examples

 and called the long last command with an added "-L/opt/local/lib" as the
 first option to "g++-4.0". After that "port install qca" completed without
 problems.

 By the way: "-I/opt/local/lib" is in my "CFLAGS" environment and many
 other ports compiled without problems. But I don't know much about
 compiling C programs, maybe I'm on the wrong track here...
