Description Giorgio Premi 2018-10-29 09:10:46 UTC
I'm generating the ebuild for Alien-SVN using g-cpan but the resulting ebuild failed to build.

The problem is that the generated ebuild use version `` but the cpan module use `v1.8.11.0`, so the resulting SRC_URI and extracted path are differents.

To workaround this issue, I simply changed 

Reproducible: Always

Steps to Reproduce:
1. g-cpan --install SVN::Client # fails
2. # fetch fails
3. replace MODULE_VERSION="" with MODULE_VERSION="v1.8.11.0"
4. # fetch ok
Actual Results:  
Modules fetch fails

Expected Results:  
Modules fetches sources and start compiling

The compilation is running right now, still don't know if it compiles ok in the end.

patch to handle 'v' versions

Came up with a patch that preserves the CPAN version if it includes the v prefix and uses this for MODULE_VERSION instead of the portage-modified version. Also created a github PR.
