Con extra-paths lo he intentado, pero veo que se añade la línea para
el sys.path [1] , pero cuando intenta instalar el egg no lo encuentra
y intenta bajarlo de internet con easy_install en lugar de construirlo
con el fuente que ha clonado mercurial.


[1]
extra-paths = /home/lm/dev/builouts/AmaraMercurial/extra-paths =
/home/lm/dev/builouts/AmaraMercurial/parts/amara

[2]
Installing amara2.
Installing 'amara'.
We have no distributions for amara that satisfies 'amara'.
