Bug#189059: libg2c0: no libg2c.so symlink

[Vincent McIntyre <Vincent.McIntyre@atnf.csiro.au>]

Hello Matthias,
thanks for your rapid response.

> Install g77-3.2, which contains this symlink.
we installed this by chance. However I made the symlink as well,
before actually trying the to build again. So it seemed to me that
adding the symlink to /usr/lib fixed things.

I didn't try building after adding g77-3.2, because had no reason to
think that g77-3.2 would provide the symlink; it seems an odd way to
do things. When I removed it again, the build still worked, because
of the link installed by g77-3.2.

I think it would be simpler from the user's point of view if there
were a libg2c0-dev package that supplied the link that g77-3.2
currently provides, or a dummy package that depended on g77-3.2.
Then, the link would be installed when the user does the obvious thing:
"oh, I want to build against that lib, I need the -dev package".
However it is probably less work for you to put g77-3.2 in the
"suggests" list for libg2c0. That would have helped me solve this
on my own.

> Is libg2c used without g77?
Not sure. We were building c++ modules and linking to libraries
built from fortran. I think g77 was being used for linking.

Cheers
