The system is Gentoo. I have tried installing rakarrack0.5.8 from portage but it fails. I also downloaded a fresh tarball and tried to installed with ./configure, make , make install command without success. Same error all the time.
I have FLTK libraries installed and they point to /usr/libfltk and also /usr/lib/fltk-1
I exported LD_LIBRARY_PATH to /etc/ld.so.conf but rakarrack still cannot find fltk libraries.
