Compile error totem on Solaris 10

[Daniel Vergien <daniel.vergien%rrz.uni-hamburg.de@localhost>]

Hi,

I try to build multimedia/totem from pkgsrc-2008Q1 on Solaris 10/Sparc.
I get an error when the configure Script tries to find the gstreamer 
playbin plugin:

checking GStreamer 0.10 playbin plugin... no
configure: error:
                                Cannot find required GStreamer-0.10 
plugin 'playbin'.
                                It should be part of 
gst-plugins-base. Please install it.

*** Error code 1

Stop.

The point is that gst-plungins-base is installed. Do I have to set 
some environment-variable to tell where to find it? I've installed 
pkgsrc under a prefix.
