[FreeJ] cannot use effectv filters

First, hello to all.
Im am learning to use freej, but i have a problem. I can only use the
frei0r filters, but not the effectv filters. I am compiling on source
on gentoo. The effectv filters appear on /usr/local/freej/lib , but
are absent from freej.

Thanks in advance
