Move Net_MAC to GitHub

Hello,

Although I haven't updated it in years, I wanted to move a package I have
in PEAR (Net_MAC) to GitHub.  I used the scripts from
https://github.com/pear/pear-svn-git however I get to "2-to-github.sh" and
I receive the error:

ERROR: Permission to pear/Net_MAC.git denied to coreone.
fatal: The remote end hung up unexpectedly
ERROR: problem pushing Net_MAC to GitHub.

I'm assuming my GitHub username (coreone) needs some permissions on GitHub
to be able to push up to this repo.  Also, would these scripts migrate the
package to PEAR or PEAR2?  It would probably make sense for it to go in
PEAR2 unless the package needs some updating beforehand.

Thanks!
