[Unison-hackers] Help building OSX GUI

[Benjamin Pierce]

All,

Sometime in the past couple of months, I stopped being able to build  
the OSX GUI version of Unison on one of my machines.  It's running OSX  
10.5.6 and XCode 3.1.2.  I've tried building both Unison 2.32 and  
2.27, with the same results.

What happens is that the build gets to this line

     /bin/sh -c "\"/Users/bcpierce/current/unison/branches/2.27/src/ 
uimacnew/build/uimacnew.build/Default/Create ExternalSettings.build/ 
Script-2A124EA10DE1C67100524237.sh\""

and then never finishes.  Investigating a little further, it seems  
that the call to

     /usr/libexec/path_helper -s

from this script never returns.  From a little googling, I see that  
path_helper is a relatively new thing in OSX, but my bash hacking  
skills are not quite up to seeing what is wrong with it on my system.

Anybody seeing similar behavior?

Thanks,

     - Benjamin
