 And hence requires that during run-time of PHP, the oracle shared
libraries for the client are available and running as well. Means: as
Oracle is not available for NetBSD, you need to check whether the
Linux-Emulation is able to install the oracle client and the client
libraries (sqlplus). Or is there an Oracle for FreeBSD?

 Indeed isnt. Only 2 days ago, another one asked how to install Oracle (as
a server) under NetBSD - and got no answers so far.y
