Hi, I just compiled gcc-4.5.0 and accidentally found that elfutils-libelf-0.145 (in at least Fedora 12) will work in place of libelf version 0.8.12 (or later) that is required per http://gcc.gnu.org/install/prerequisites.html
I suggest adding sentences something like this to the prerequisites page: The package elfutils-libelf-0.145 (or later) also supplies the libelf prerequisite. Version 0.142 does not work. (versions 0.143, 0.144 unknown) A search found that H.J. Lu had already reported what I discovered: http://gcc.gnu.org/ml/gcc/2010-03/msg00127.html Don
