Workaround for Snow Leopard (10.6) issue with osascript command

If you see this bizarre error when using the osascript command:

2011-02-01 14:11:28.727 osascript[11990:903] Error loading /Library/ScriptingAdditions/Adobe Unit Types.osax/Contents/MacOS/Adobe Unit Types:  dlopen(/Library/ScriptingAdditions/Adobe Unit Types.osax/Contents/MacOS/Adobe Unit Types, 262): no suitable image found.  Did find:
        /Library/ScriptingAdditions/Adobe Unit Types.osax/Contents/MacOS/Adobe Unit Types: no matching architecture in universal wrapper

it apparently has to do with the mixing of 32 and 64-bit architectures. I don't know what the real fix is, but the workaround is to force osascript to use 32-bit like this:

arch -i386 /usr/bin/osascript -e '[your applescript]'
