Yes, Fedora-13 decided to use ld scripts as .so files, instead of having .so's as expected binaries. Maybe next time .txt files will be binaries that are vi/emacs plugins, who knows. Anyway, to handle this case we did modify ./configure to make do an explicit link to find out if the referenced file is a 64-bit library or not.

Cheers, Fons.
