Just a small observation: REcently it seems to me that after building gretl from cvs I always have to do 'sudo ldconfig' before I can make gretl start. I don't have hard evidence to support this, though. I'm mostly using Ubuntu 11.10 (and its derivatives like Mint; this observation does not seem to happen just on one machine/platform), maybe something changed from 11.4 to 11.10? cheers, sven
