Hi Danny!

Thanks for the push.

Oh no, that patch is required. MS won't build with srtp enabled, without it. 
You can see "MediaStreamer will be built without SRTP support". That patch 
fixes search and locate of srtp2 version of include and lib files.

Shall we please keep the name "mediastreamer" for package and "mediastreamer2" 
for variable? The release tarballs have not been renamed. We'll change the 
package name when it is changed in releases by upstream. This will consistent 
with other packages in linphone.scm.

Regards,
RG.
