Non-root install doesn't work

Attached typescript of failed session on Fedora 28 (Perl 5.26.2).

Looks like some defaults have change in MakeMakers. In the main Makefile, try changing this

-       cd $(LIB_SUBDIR) && perl Makefile.PL INSTALLDIRS=$(PERL_INSTALLDIRS) 
+       cd $(LIB_SUBDIR) && perl Makefile.PL INSTALLDIRS=$(PERL_INSTALLDIRS) INSTALL_BASE=$(PREFIX)

This makes "make install PREFIX=blabla" work here.

Almost, but when I actually run llgal afterwards I get:

Could not locate Llgal/Config.pm in @INC

I need to push /usr/local/packages/llgal/lib/perl5 onto @INC in llgal.in, but how to do it in a generic way? I tried "@LIBDIR@" and "@INSTALLSITELIB@" but neither of these gets replaced by make install :-(

I don't remember well why, but I used to just adjust PERL_INC in my environment.

Can MakeMaker do autoconf-style text replacement in the files it installs? Maybe the installation of the llgal script should also go through MakeMaker and not with a hand crafted Makefile?
