[meta-freescale] PREFERRED_VERSION question - do_rootfs stage can't find library

[Ashwin Kirpalani]

I am using the master branch and am building latest ver 3.6.1 of linphone (
https://www.linphone.org/) using a recipe I wrote. This recipe has a
DEPENDS = pulseaudio as one of the dependencies. The version of pulseaudio
in the current poky recipe tree is 4.0, so when I 'bitbake fsl-image-gui',
I get the following error:

fyi...libmediastreamer is one of the main components of linphone.
Apparently, linphone needs the specific library
*libpulsecommon-3.0.so*<http://libpulsecommon-3.0.so>
* * even though libpulse > 3.0 requirement is there (i.e.
libpulsecommon-4.0 won't work)

So I created a recipe for pulseaudio_3.0.bb and added the following to my
conf/local.conf:

PREFERRED_VERSION_pulseaudio = "3.0"

Now here's the part that I am confused as to how to overcome. After I add
the above line to my conf/local.conf:

When I build core-image-x11, I get past the above error and I can build the
image and run the linphone application on the target (which is a sabrelite)
When I try to build the fsl-image-gui, I get the following error:

So it seems that when I build *fsl-image-gui*,
*libpulsecommon-3.0.so*<http://libpulsecommon-3.0.so>
* * can't be found during the do_rootfs stage (even though it has been
built and I can see it
at /home/ashwin/yocto_master/build/tmp/work/armv7a-vfp-neon-poky-linux-gnueabi/pulseaudio/3.0-r0/package/usr/lib/pulseaudio/
libpulsecommon-3.0.so). This problem does not occur when I build *
core-image-x11.*

Can anyone help with this please? Thanks
