Everything in the man page and examples still work for me.

Feel free to fix it as you see fit then.

I did at length already on this list.  After the release feel free
to send patches and/or logs.

I always run everything over SSH, os if SSH is your problem then it
is miscocnfigured.

Works for me:

$ gpscat -V
gpscat: Version 3.20.1~dev
gem@spidey ~ $  ssh localhost /usr/local/bin/gpscat -V
gpscat: Version 3.20.1~dev

Since it only happens to you, hard for anyone else to fix.  I suspect you
are correct that your environment is wrong somehow.

As always, full build logs are just the start.
