    <p>Installed Ubuntu 11.10, removed Ruby1.8.7 completely, and then installed Ruby1.9.2-p290 from source, followed by rubygems1.8.10.

Similar upgrades worked when, in another machine, I had gone from 1.8.7 to 1.9.1. I have tried providing all the details, making this a long question. Any help at all will be greatly appreciated.</p>

    2. COEven though the problem was solved quite some time back by virtue of Dylan's answer below, thank you for pointing out this point. Yes, `which irb` does indeed return `/usr/bin/irb`

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
