multimedia/gstreamer0.10 problems on Sparc Solaris

[raymond.meyer%rambler.ru@localhost]

I can't build gstreamer0.10 on Sparc Solaris with Sun compilers:

===> Building for gstreamer0.10-0.10.24
Making all in gst
Making all in parse
  CC    lex._gst_parse_yy.o
"parse.l", line 5: cannot find include file: <glib/gprintf.h>
"../gst_private.h", line 36: cannot find include file: <glib.h>
"../../gst/gstplugin.h", line 32: cannot find include file: <gmodule.h>
"../../gst/gstobject.h", line 29: cannot find include file:
<glib-object.h>

.. and so on

Any ideas why glib2 include files are not found?
