I'm having some major problems with PackageMaker and I have some clues
that might help figure out what's going on. I have an app I created
from an Applescript, I saved it as an application. Using "Get Info" in
Finder tells me that it's 60 KB. Using Terminal "ls -l" tells me that
the exact same app is 13780 bytes large... that's the first strange
part (apps created with applescript apparently aren't folders like
regular apps). Now I've created a package using PackageMaker which
just installs that app to the /Applications directory. I changed the
permissions to rwxrwxr-x, chown'ed the owner to root, and group to
admin per tutorials on PackageMaker. So I build the package... When I
run it and it supposedly installs, I get an app in the /Applications
folder with an icon with a circle & line through it. When I try and
run it, it says, "You can't open the application 'MyApp' because the
Classic environment is no longer supported." The file size in Finder
now says it's 16KB large compared to the 60KB file I added to the
package (but remember in Terminal it always said it was 16KB). Now if
I manually copy the app to the /Applications folder, it works fine.
FYI - I am using a PowerPC notebook with 10.5.2 installed, fully
updated. Any ideas as to why the filesize is different depending on
what I use to view it? And any ideas why it's copying an apparently
corrupt file to the /Applications folder?  I honestly don't understand
why it's so difficult for PackageMaker to do something as simple as a
copy & paste.

BTW, I have to do this with an installer because I have plug-ins that
need to be installed elsewhere.
