Hi! There is a small bug in the spec-file included in the CLN package "http://www.ginac.de/CLN/cln-1.1.13.tar.bz2". The package is compressed by "bzip2" and has extension ".bz2", but the spec-file refers to a "gzip"-compressed file with extension ".gz", so the command rpmbuild -ta cln-1.1.13.tar.bz2 fails. A workaround could be to uncompress the file and re-compress it with gzip, but this is somewhat inconvenient, and the issue is easily fixed by replacing ".gz" by ".bz2" in the spec-file.
