I am trying to SCL-ize a set of spec files generated by cpanspec and spec2scl consistently modifies the line
Requires: perl(:MODULE_COMPAT_%(eval "`%{__perl} -V:version`"; echo $version))
to be
%{?scl:scl enable %{scl} '}
Requires: %{?scl_prefix}perl(:MODULE_COMPAT_%(eval "`%{__perl} -V:version`"; echo $version))
%{?scl:'}
But the preamble isn't a script so this should probably be changed to:
Requires: %{?scl_prefix}perl(:MODULE_COMPAT_%(eval "`%{?scl:scl enable %{scl} '}%{__perl} -V:version%{?scl:'}`"; echo $version))
but actually in a Perl SCL environment %{__perl} is defined as "%_scl_root/usr/bin/perl" so the wrapping in "scl enable %{scl}" is not necessary, so the wrapper lines could just be dropped in the preamble.
This has been fixed by [1]. In the newest spec2scl, evaluating the above line gives
Requires: %{?scl_prefix}perl(:MODULE_COMPAT_%(eval "`%{__perl} -V:version`"; echo $version))
which should be exactly what you need. This is a part of update that I just pushed to stable on F18 and EPEL6. So you will be able to install via yum soon (if you're using python's easy_install or pip to install newest scl, you can of course install from there, too).
