no.
when i said "use the 'reportbug' cmdline tool" i meant "please use the
'reportbug' cmdline" tool, like that:

     reportbug gem
Ok. It was clear that it's a cmdline tool, I was just not aware of it.

'reportbug' is a tool installed on Debian and derivatives to report bugs
against system installed packages.
since the bug you are experiencing has nothing to do with Gem itself but
*only* with the "gem" package provided by your distribution, you should
report a bug with your distribution, and not on the pd-gem sourceforge
bugtracker (and not at all at the pure-data sourceforge bugtracker).

this is explained here

Did it, hope I did it right...
