oh, the problem is compress/uncompress command lost on rh8/mandrake9. copy one from old version. or update your install file, use 'gunzip' to replace 'uncompress'.
try it.
it includes two files: 1. common.g.z 2. linux.g.z. The common file includs .install.now that it can install auto. The linux file including real information for scl
suggestion to solve scl1.2 installation in redhat8 is that run/install scl1.2 in redhat7.3 and then, copy the whole scl directory to redhat8. then, run the lmgrd as appropriate.
