phpwebsite ebuild depends on mysql explicitly. According to their website, they use PEAR, and so don't depend on anh particular database.
Never mind. Close this bug. I just tried it with PostgreSQL and it doesn't work at all. The developers claim that next version should be coming out over the summer and will fix this.
closing as requested.
right, could be removed who says the db runs on the same host ?
mholzer: you'd still need mysql on your local machine as php needs to link against it if you want the mysql functionality (even if you don't use it directly, the PEAR DB code does).
