linphone containts its own libgsm under libgsm. If you investigate
in mediastreamer2, you can see that library used for linking is library
from linphone. Therefore if you have installed gsm-devel, header files are
taken from /usr/include, but object file from linphone/libgsm. This is bad and
should be fixed. Linphone should use header and object files from one location
at one time.

We can remove libgsm subdir from linphone's sources, create explicit check
in for gsm-config and change mediastreamer2/ to use
system wide libgsm. (This is my favourite option.)

Or we can use my patch (How does it break your system exactly? I have no
system wide libgsm installed) to use internal implemetation only.

Finaly we can make the location of libgsm library and header files compile
time configurable via configure parameter.

How do you vote?
