I've had a similar problem with my first installation.
Are you using open_basedir?
If yes, check the open_basedir entries. You have to be able to access the php libs (e.g. under /usr/share/php)

In my case, once I correctly set the open_basedir entries, the installation worked fine.

On the first page the response by the Roundcube Installer is:

However, when I click on NEXT I get this error page:

"Internal Server Error" .. bla ..bla..

My logs show this error:

Any idea what this error means? I googled thru and there was a similar issue which turned out to be the requirement for mdb2 driver for Mysql, so I have also installed this driver, but again, I am getting the same error.
