Re: lepl question

[andrew cooke]

Hi,

There's a *huge* difference between Lepl 2.7 and 5.0. I would guess that this
is either a result of some change in how Lepl works between those versions or
a bug in Lepl 5 (not Mac-specific).

In general, later version of Lepl are improvements, but major version number
changes (2->3->4->5) do break some existing code. So if you have code that
run on Lepl 2.7.4 and you simply want to keep using it elsewhere then you are
best installing the same version of Lepl on the Mac. Use:

easy_install "lepl==2.7.4"

to install that version.

If you want me to help with fixing your code to work on 5 and/or fixing any
bug there might be in Lepl then I need some more details. Can you make a
small example that shows the same problem?

Thanks,
Andrew
