I tried to install sylpheed claws, V1.0.4a, and here is the ./configure error I got: checking for glib-config... /opt/gnome/include/glib-2.0/glib.config checking for GLIB - version >= 1.2.6... no *** Could not run GLIB 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 GLIB was incorrectly installed *** or that you have moved GLIB since it was installed. In the latter case, you *** may want to edit the glib-config script: /opt/gnome/include/glib-2.0/glib.config configure: error: Test for GLIB failed. See the file 'INSTALL' for help.
