Hi,
I'd prefer to change this by patching the llist.h of Ganglia. Does anybody
have objections to this?
Over the long term it would make sense to either build ganglia with libe or
maybe even integrate libe into ganglia and produce the libe RPM when building
ganglia. I saw that gexec is also integrated into the ganglia SVN tree: is
this now the main development tree for gexec?
Thanks,
best regards,
Erich
