Hello! I just realized that no guile-gtk interpreter was built with the guile-gtk-0.21pre4 package. Only the build-guile-gtk script is built. ftp://geek.mine.nu/pub/SRPMS/guile-gtk-0.21pre4-2.src.rpm ftp://geek.mine.nu/pub/RPMS/guile-gtk-0.21pre4-2.i686.rpm ftp://geek.mine.nu/pub/RPMS/guile-gtk-devel-0.21pre4-2.i686.rpm ftp://geek.mine.nu/pub/RPMS/guile-gtk-static-0.21pre4-2.i686.rpm Here is a Makefile.am patch that fixes it.
