Compiling Mac app doesn't work

[phette23]

There are multiple problems with compiling the Mac app. Following the readme instructions and running package-mac/ebi-package.command:

• python setup.py py2app --iconfile ebibig.icns --plist Info.plist fails because neither of the referenced files (ebibig.icns, Info.plist) exist under package-mac nor source
• the app that's compiled is 32-bit & thus doesn't run on Catalina
• I get hdiutil: internet-enable: verb not recognized, I suspect this step is unnecessary
• I always get "mv: cannot stat 'dist/ebi.app/Contents/MacOS/ebi.command': No such file or directory" and "hdiutil: create failed - Resource busy" but if you run these package commands manually one-by-one after doing py2app they succeed, so I'm not sure what's going on there

I tried the most basic set of fixes I could think of: remove the --iconfile & --plist flags, remove the arch property from the OPTIONS dict in setup.py (I also tried using 'arch': 'x86_64'), delete the internet-enable command. The result successfully creates dist/ebi.app and dist/ebi.dmg but the app cannot be opened. I see errors like

"spawn_via_launchd() failed, errno=111 label=org.pythonmac.unspecified.ebi.7300 path=/Applications/ebi.app/Contents/MacOS/ebi flags=1"
"Non-fatal error enumerating at , continuing: Error Domain=NSCocoaErrorDomain Code=260 "The file “PlugIns” couldn’t be opened because there is no such file." UserInfo={NSURL=PlugIns/ -- file:///Applications/ebi.app/Contents/, NSFilePath=/Applications/ebi.app/Contents/PlugIns, NSUnderlyingError=0x7f899a645dc0 {Error Domain=NSPOSIXErrorDomain Code=2 "No such file or directory"}}"

in Console.app.
