I believe your problem might be there. Before you showed the output of "rpm -q gtk2-devel" and it showed it twice, which indicates you have both i386 and x86_64 versions installed, I believe you should have the x86_64 version only. Try to uninstall the 32-bit version with the "yum erase gtk2-devel.i386" command. Also, check that the version of "pkgconfig" and "cairo-devel" you have installed are the x86_64 versions. You can do that with this command (and expected output): $ rpm -q --qf '%{name}-%{version}-%{release}.%{arch}\n' pkgconfig cairo-devel pkgconfig-0.21-2.el5.x86_64 cairo-devel-1.2.4-5.el5.x86_64 That might shed some more light on that issue. Once you get "pkg-config" to work again, try to rerun your ./configure and see if it works now as you expect. BTW, what exactly are you building? Did you try to see if someone managed to package it as an RPM before? That might help... HTH, Filipe
