jhbuild bootstrap: can't install waf

[Rafael Wild <rafael_wild yahoo com br>]

Hi.

I downloaded jhbuild:
$ svn co http://svn.gnome.org/svn/jhbuild/trunk jhbuild

and installed it. I created a .jhbuildrc from sample and changed these
lines:
moduleset = 'gnome-2.24'
modules = [ 'evince' ]

Then I tried to bootstrap it:
$ jhbuild bootstrap

It begins to download and compile a lot of things, but then it stops
when installing "waf":

*** Installing waf *** [13/14]

Does someone know something about this?

Thanks
