I found .spec files for Perl are surprisingly hard to come by.  I ended up
writing my own.

I'm not using Perlbrew, but here's my .spec (appended) with a makefile and an
.rpmmacros file. The makefile downloads and builds the Perl version named in the
PERL_VERSION variable, then builds an RPM called "my-perl" which installs in
/opt/perl.  Obviously you could modify this to be whatever you like.

I don't bundle any extra cpan stuff in there, but you could, and I don't think
you'd need to change the .spec much, if at all.  Of course, you'd need to add a
target to the makefile to install the stuff you need.

We use this RPM as a base, and use local-lib installs to supplement it for
development, and (intend to) use git snapshots of applications complete with
local-lib for production deployment (it's still work in progress).

I started off using FPM [1], and then tweaked the spec our own ends.  (FPM
didn't work so smoothly at the time, some now-fixed bug I don't remember the
details of, but this .spec doesn't need it anyway.)


Cheers,

Nick
