Hi, I don't think this is fully fixed. On current master, trying to run
po4a (a perl application that guix now depends on to generate the
translation of the manual), I get the following:

[env]$ po4a-updatepo
Can't locate Locale/Po4a/Po.pm in @INC (you may need to install the
Locale::Po4a::Po module) (@INC
contains: /gnu/store/b10z3mm4nyvzwq6b7537nhckmilbv7bm-po4a-0.47/lib/perl5/site_perl /home/tyreunom/.guix-profile/lib/perl5/site_perl /home/tyreunom/.guix-profile/lib/perl5/site_perl /home/tyreunom/.guix-profile/lib/perl5/site_perl /gnu/store/43vb2vnv7alwi40ms5qsb9i84rs0xb6s-perl-5.26.2/lib/perl5/site_perl/5.26.2/x86_64-linux-thread-multi /gnu/store/43vb2vnv7alwi40ms5qsb9i84rs0xb6s-perl-5.26.2/lib/perl5/site_perl/5.26.2 /gnu/store/43vb2vnv7alwi40ms5qsb9i84rs0xb6s-perl-5.26.2/lib/perl5/5.26.2/x86_64-linux-thread-multi /gnu/store/43vb2vnv7alwi40ms5qsb9i84rs0xb6s-perl-5.26.2/lib/perl5/5.26.2)
at /gnu/store/b10z3mm4nyvzwq6b7537nhckmilbv7bm-po4a-0.47/bin/.po4a-updatepo-real
line 168.

What fixed the issue was adding
$GUIX_ENVIRONMENT/lib/perl5/site_perl/5.26.1 to the PERL5LIB variable.

It used to work until very recently, but I wonder why the version number
is 5.26.1 if perl is 5.26.2?
