#2 ibdriver-1.2.8 download has wrong file extension

[Scott McKenzie]

ibdriver-1.2.8 is downloaded as a tar.gz file, however
this file is not gzip'd. e.g.
# tar -zxvf ibdriver-1.2.8.tar.gz

gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error exit delayed from previous errors

Whereas:
# tar -xvf ibdriver-1.2.8.tar.gz
successfully unpacks the archive.
