Is this the MET Fortran package? It sounds like it. If so, the
situation is that I agree with you entirely and I got the same
answer
from them.
I do believe that if the program is distributed (even in purely
source
form) it should be under the GPL, a compatible license, or public
domain.
On a somewhat related note, can users of the GSL choose to make
their code GPLv2 if it is still compatible with the 'old' GSL
versions that didn't have GPLv3?
While that might be possible I don't think it would be desirable, if
someone wanted to use "GPLv2 only" for everything it would prevent
people from using their code with new versions of the GSL under
GPLv3.
The GPLv3 is a state-of-the-art free software license and I would
encourage everyone to use it.

IANAL, but I think there are only three legal ways to use GPL
licensed code
(1) Do what ever you want but do *NOT* distribute the code at all
(2) License derivative work under GPL and distribute
(3) License your code under your favorite license, distribute (in
source form) without GPL code and let end-user to download GSL,
compile it, compile your code and link it all together. This is the
worst distribution method for the reasons that are quite obvious.

IMHO, your method (3) is not correct at all. please have a look on
last lines of GPL
I think copyright include function names, algo details and even
names of variables so, with GPL, you can NOT use them in a non GPL
compatible source code.
But I want to say that the ideas (algo) are completely free.
