Please can you add libmath-random-perl to the whitelist for non-free
autobuilding. According to debian/copyright, the reason for it being
non-free is due to restrictions that prevent copying/distribution for
"direct commercial advantage". As far as I can see, this does not prevent
the module from being auto-built.
The copyright already states that the package is auto-buildable. I will add
the XS-AutoBuild field to the control file in our svn repo (to be included
in the next upload) if I receive an ACK from you.
The full copyright for the non-free portions of the package, for reference:
