Continuing the build process (the make command) I see this error. Would it be possible to notice this already in the perl Makefile.PL step and stop the process there?
Gabor checking for GTK+ version... checking for pkg-config... /usr/bin/pkg-config checking for GTK+ - version >= 2.0.0... no *** Could not run GTK+ test program, checking why... *** The test program failed to compile or link. See the file config.log for the *** exact error that occured. This usually means GTK+ is incorrectly installed. configure: error: The development files for GTK+ were not found. For GTK+ 2, please ensure that pkg-config is in the path and that gtk+-2.0.pc is installed. For GTK+ 1.2 please check that gtk-config is in the path, and that the version is 1.2.3 or above. Also check that the libraries returned by 'pkg-config gtk+-2.0 --libs' or 'gtk-config --libs' are in the LD_LIBRARY_PATH or equivalent.
