Good.

Don't worry, beta-testers are as necessary as developers. In a way, it's
like making a QSO, someone has to answer the call, and give a report :-)

Will fix that.

This looks like the buggy version of Hamlib from your distro.
Where have you been installing the re-compiled Hamlib? /usr/local ?
You can test grig against it by setting the following in your shell:

	LD_LIBRARY_PATH=/usr/local/lib:"$LD_LIBRARY_PATH"

I've attached ft100.c to replace yaesu/ft100.c in your tree. You may
also simply wait for tomorrow to get the nigthly snapshot from bleeding-edge.

Cheers
