I'm in the same situation. According to my research, these are the 
options:

1. Using Python zipfile - the easiest way but does not support 
resource forks:

    # zip the contents of folderPath in archivePath

    import os
    import zipfile

    prefixLength = len(archivePath)

    zip = zipfile.ZipFile(archivePath, 'w', zipfile.ZIP_DEFLATED)

    for root, dirs, files in os.walk(folderPath):
        for file in files:
            # You may exclude files here, change file archive name etc.
            fileName = os.path.join(root, file)
            archiveName = fileName[prefixLength:]
            zip.write(fileName, archiveName)

    zip.close()
   

2. Using ditto (is it available on every mac?):

   ditto -ckX "/path/to/folder" "/path/to/ArchiveName.zip"


3. Using minizip library, part of zlib distribution - did not check yet.

zip command line tool is annoying, I would not use it.
