Created attachment 350896 [details, diff] Patch against mail-client/roundcube-0.8.6 ebuild to add proper sqlite support The attached patch adds the 'sqlite' USE flag to the roundcube ebuild, and makes it require dev-php/PEAR-MDB2_Driver_sqlite in that case. With this simple addition, roundcube using sqlite as a database backend works correctly here.
sqlite was dropped on purpose until sqlite3 support was added in >=roundcube-0.9. If you want sqlite support use >=roundcube-0.9.
