Great Matt, I FIXED it.
Since you're working on a debian system, I will ask whether you installed Ifeffit from source and are using the PGPLOT installed from PGPLOT_install, or are using debian packages for these? If you're using debian packages for Ifeffit or PGPLOT, please remove these and reinstall from source.
It was exactly a problem with pgplot library. I recompiled pgplot by source
and linked the generated-by-source libpgplot.so
NOTE: In the meantime I have pgplot5 installed as debian package (but it
works too).
Sorry for annoying you with my "distribution" problems.
On the other hand, I would like to propose an upgrade in the "horae_update"
script, that is supporting proxy server to fetch upgrades.
Thanks again,
Mauro.
