If you have libspeex-dev installed when configuring opal, then opal.pc 
will contain:
  Requires: ptlib speexdsp
This means that libpt-dev and libspeexdsp-dev must be installed when 
configuring a program which uses opal.pc, such as ekiga.

However, this is wrong, because ekiga program does not need 
libspeex-dsp, but libspeex.

I do not know how to impose to a program to require a library (not its 
headers) through pkg-config (but it might exist somehow).

I repeat: the question is: how opal can tell ekiga that libspeex (not 
-dev) is needed in order to use opal?
