Oh, it's not even close to being forgotten--I've applied a fix :)

I think >= 2.90 should work; at least, it doesn't look like the soname
has changed since before 2.90 was released.

I guess we should actually have a check in ./confgure that checks the
version of libgps and aborts if a sufficiently-high version is not
available....

There's a sufficient version of libgps-dev in Ubuntu as of 10.04 (Lucid);
in Debian, libgps-dev 2.94 is available in Squeeze (Debian's current
`testing' branch), and appears to install and work fine on Debian 5.0 (Lenny);
I don't know about Ubuntu, but I'd bet that one can install the libgps
packages from Lucid on Karmic--libgps is very light on dependencies.

Is it worthwhile trying to support both the new and old libgps APIs,
do you think?
