[bug#28802] [PATCH] gnu: Add paml.

Hi Roel,

Oh, that’s too bad.  Do you have a test case we could use to verify that
the tools work correctly after installation?

It doesn’t seem to be easy to fix this, as variables in which file names
are stored are size-restricted, and as they are copied around multiple
times it is difficult to ensure that our patch wouldn’t break things.

Here’s an untested draft of the new phases, but I suspect this would
take a lot more work:

The alternative is to just install the data files to $out/share/paml and
expect users to copy them to their current working directory.  That
seems to work.

I prefer this over patching the code, which is much too invasive.

What do you think?
