Howdy William. Thanks for the quick response.

Yes, just downloaded your frameworks again today and yes I am using 
install_name_tool to change the reference to match the QGIS binary 
distribution.

I don't think it does and I want to say that that is the same across 
minor numbers as well. When I first started trying to compiled for OSX I 
my QT version was one minor version number different (newer) and the 
plugin would not load. Once I changed Qt versions it loaded up just fine.

I tried the version from your site Qgis 1.0.0-1 for Leopard. It 
immediately crashed at first. Seems that the GDAL 1.6 framework requires 
postgres, though it is not listed as a dependency. Once I installed the 
postgres framework qgis loaded but when I add my plugin it crashes again

There is still a different in the GEOS version numbers. The north arrow 
plugin shows GOES lib compatability version 4.0.0, current version 
4.1.0, when I build with your GOES framework ( 
GOES_Framework-3.0.3-1.dmg ) that is online, I get compatability version 
4.0.0, current version 4.0.3

aye, it would be good to hear if any other folks have had trouble.


Thanks for you time.
