[Pythonmac-SIG] py2app failure with framework build of 2.7

[Nat Echols]

Replying to my own post: after sending this, I read the section in the
documentation about "alias mode".  This seems to work fine, and
produces an app that is 50KB instead of nearly 9MB.  Since I'm running
this script as part of a complicated build and installation process,
and the path to the interpreter and all modules is frozen by the time
I need to make my app, it would seem that alias mode should work fine
for actually *deploying* my software.  Is there any drawback to doing
this?

thanks,
Nat
