I tried somethings; one of them makes 3e2add75. I don't know what's exactly work but https://gitorious.org/guile-sqlite3 display "sunjoong committed 3e2add75 on April 30, 2012 13:23". Now, the time to "pull request."

What it means is to go to:

https://gitorious.org/guile-sqlite3

Create an account and log in. Then go back to:

https://gitorious.org/guile-sqlite3

And click "Clone this repository". That will give you a Git repository
for guile-sqlite3, on gitorious.

Then, you do the "git clone ssh://....", make your change, "git commit"
it locally, then "git push" to the origin.

When that is done, there is a button in the web interface to "request a
pull", meaning, request that dzu (or me) merges your changes to the
"main repository".

Thanks.
