bug#56144: perl-mail-spf package installs, but does not run.

[Eduard Budulea via Bug reports for GNU Guix]

Hello all,

I am trying to have a guix system that has exim with spf validation 
(sadly the exim that is packaged with guix has spf disable) and I am 
trying to run the external tool spfquery.

spfquery binary is in the perl-mail-spf package.

The package builds and deploys.

But when when I try to run it, I get:

Can't locate Error.pm in @INC (you may need to install the Error module) 
(@INC contains: 
/gnu/store/hy6abswwv4d89zp464fw52z65fkzr7h5-perl-5.34.0/lib/perl5/site_perl/5.34.0/x86_64-linux-thread-multi 
/gnu/store/hy6abswwv4d89zp464fw52z65fkzr7h5-perl-5.34.0/lib/perl5/site_perl/5.34.0 
/gnu/store/hy6abswwv4d89zp464fw52z65fkzr7h5-perl-5.34.0/lib/perl5/5.34.0/x86_64-linux-thread-multi 
/gnu/store/hy6abswwv4d89zp464fw52z65fkzr7h5-perl-5.34.0/lib/perl5/5.34.0) 
at /run/current-system/profile/bin/spfquery line 335.

BEGIN failed--compilation aborted at 
/run/current-system/profile/bin/spfquery line 335.

If I add all its dependencies to packages and populate the PERL5LIB 
environment variable with the paths to the needed libraries from 
/gnu/store then it works.

So it is basically a packaging problem.

I have tried to move the dependencies from input to input-propagated, 
but got the same result.


Any ideas?

Thanks.

Even if that did work, installing perl-mail-spf would then also 
install these other perl-* packages — no better than a traditional 
distro.  Avoid propagation wherever possible.

Instead, you should ‘wrap’ the spfquery executable so that 
PERL5LIB is correctly set when it's invoked, without polluting the 
user's profile.

Look at the ‘dirvish’ package for an arbitrary but seemingly sane 
example.

Kind regards,
