> Ah thanks James. Since we use multiple local libs for different apps then I
can't use the perl version-specific library so I think I'll have to go for
your suggestion of a wrapper script for switching. I thought I'd check
before writing such a beastie or looking at a patch in case other users of
perlbrew had come across a similar problem, which if you're using a
heterogenous environment with multiple apps is very likely.
