See that "X" in every error? Seems like a bad substitution or something similar. Any idea where that "X" comes from? Did you accidently edit autogen.sh? Or perhaps your CentOS VM is an older version than your RHEL you use at home and the programme you are building needs more recent libtools? I reckon that onces you get rid of those X-es things should build fine. Regards, Leonard. -- mount -t life -o ro /dev/dna /genetic/research
