Dear Guix,

The attached patch would add perl-pathtools.  This package searches for
the “pwd” program in specific paths (ignoring the PATH environment
variable).  Because “pwd” is part of “coreutils”, it has a funny
dependency.

In the path I substitute the entry for “/bin/pwd” to the store path of
coreutils's “pwd”.

Is this the right way of packaging perl-pathtools?

Kind regards,
Roel Janssen
