Perl modules in Ubuntu that do not adhere to Debian's naming policy
Ubuntu includes several Perl module packages that do not adhere Debian's
naming policy. Once Debian includes these modules in a differently
named package, there are problems if one tries to install both packages
at the same time. See  or  for examples.
It is cumbersome to solve these bugs: to correctly address these issues,
one would have to add an "Replaces: <old-package>", creating an
unnecessary diversion from Debian.
To avoid these problems, Ubuntu should rename the packages not yet
adhering to the naming policy. I do not know which packages in Ubuntu
are affected by this though.
