The best way I found to transfer the contacts, was to export the contacts from the Android device to the SD card, import that to GMail, export from GMail in Outlook CSV format, import that to Outlook and sync contacts with the BlackBerry desktop app.
You cannot go direct because Outlook does not support importing more than one contact per VCF file, and phone numbers will not sync to GMail automatically unless they also have an email address on them.
