Hi,
I made some changes to mac_packager,
it's not the maximum but it works.
I also created an app bundles for aMuleGUI, the icon is not so good

mac_packager changes
if amuled, alcc and cas exist, it copy them in MacOS
it copy skins in SharedSupport
it copy the webserver templates in SharedSupport instead of Resources:
so amule sees them, but amuleweb search them in /usr/local/share/amule/webserver
(I temporarily use a symlink)
if amulegui exists, it populates the aMuleGUI bundle
it copy all the required MacPorts libraries from /opt/local/lib to Frameworks and it update their info
I'm sorry for my bad English

Goodbye,
Gianluca.
