Such code PackageFile.write(struct.pack( "l", PkgHdrSize)) have different behaviour on 32-bit and 64-bit systems. In case 32-bit system it writes to file 4 bytes. and 8 bytes in case 64-bit system, but in http://docs.python.org/library/struct.html p.7.3.2.2 long type have strict 4-byte size. |

This is expected behaviour. By default, struct.pack and struct.unpack use the *native* size and alignment. Use "<l" if you want platform-independent behaviour. Relevant docs: http://docs.python.org/library/struct.html#byte-order-size-and-alignment |
