[Zope] Building from Source

[Ben Ocean]

Hi;
One of the add-on programs I want to include (ZMySQLdb) requires I rebuild
Zope from the src-tgz distro. I've tried to do this but get this error:

gzip: stdin: invalid compressed data--crc error
tar: Child returned status 1
tar: Error exit delayed from previous errors

Now, I *was* supposed to upload it as an ASCII file, right? If that's so,
can someone please explain to me what I'm doing wrong?
TIA,
BenO
