http://www.kotnet.org/~skimo/isl/isl-0.08.tar.bz2 copying isl-0.07-r1.ebuild to isl-0.08.ebuild works fine here, but watch out for the new CLANG check in configure.ac -- i'm not sure if the ebuild needs clang/llvm in deps now(?)
Thanks. Looks like some kind of bindings-generation system. http://repo.or.cz/w/isl.git/commit/1157635374e1cc1ade4cc5c056012a7da1407c48 It defaults to no so I'll leave it disabled until someone requests it.
This version breaks cloog-0.16.3. Need to wait for a new release.
Fixed.
