Re: [Audacity-devel] Error building (with python3 as /usr/bin/python)

[Lasse S. B. <las...@gm...>]

I've just upgraded os x (to Lion) and downloaded audacity sources again via
svn.
./configure couldn't complete because of a missing *python2*, it stopped in
this section:
=== configuring in lib-src/lv2

So I did this:
  sudo ln -s /usr/bin/python /usr/bin/python2
... and it ran without further errors.

Is that how it's supposed to be done for now?
