ERROR: bin/stow contains 'use lib' line which could interfere
with CPAN-style installation via Module::Build.  To avoid this,
you should run ./configure with parameters which result in
--with-pmdir's value being in Perl's built-in @INC, and then run
'make' (NOT 'make install') to regenerate bin/stow, e.g.

    eval `perl -V:siteprefix`
    ./configure --prefix=$siteprefix && make

or

    ./configure --with-pmdir=`PERL5LIB= perl -le 'print $INC[0]'` && make

Then re-run this script.

Note that these parameters are chosen purely to regenerate
bin/stow without a 'use lib' line, so don't run 'make install'
while Stow is configured in this way unless you really want an
installation using these parameters.
