The rssowl shell script on x86_64 has XPCOM=$(ls -t /usr/lib6464/mozilla-*/libxpcom.so|head -n1) which is incorrect because it should be lib64 not lib6464. I suggested this approach originally. That code shouldn't even be there now, though (it was removed from the eclipse script, when we still _had_ an eclipse script), because SWT now uses gre.conf to detect mozilla, as I understand it.
My mistake. That code is still needed - obviously only eclipse uses gre.conf, not rssowl. The lib6464 thing just needs fixing.
I fixed this the other day in version rssowl-1.2-12.fc5, which still hasn't hit the extras repository yet for some reason. I'll look into that. In any case, I'm closing this with NEXTRELEASE. Thanks Robin! AG
