I have just installed Ubuntu 9.10 on a old computer. I downloaded the current version of the gretl source and, after the usual process of installing missing libraries, it compiled without any problems. However, when I try to run gretl I get an error message saying "symbol lookup error: /usr/bin/gretl_x11: undefined symbol: get_gretl_rc_path. My understanding is that gretl creates the file gretl2rc. when it first runs. I have ensured that there is not an old version of this file hanging around. What else do I need to do? Incidentally I have checked that this does not happen when I install the earlier version of gretl (1.8.1) from the Ubuntu repository, but I need to use the current version to tidy up some of my functions before re-releasing them.
