I seem to experiencing erratic behavior   with the settings of these two 
parameters:-

--extra-ldflags=
--extra-clflags=

in the configure script of mythtv-0.23.1 for both the released tarball and   
that available from svn as of yesterday.

----------A
I have both dvdnav and dvdread installed in /opt (Both are  used succefully 
in the  compililation of  other programs such as vlc, kde4.4.5 etc.
For the present setup,
If I set --extra-cflags=/opt/include
I get the make error reported above.  Here it seems  there is conflict with  
the  pre-installed headers in /opt(or/usr)/include/{dvdnav,dvdread} and stuff 
in  ~$SOURCES/mythtv/libs/libmythdvdnav
If I set --extra-cflags=-I$SOURCES/mythtv/libs/libmythdvdnav
the make error dissappears  revealing more make errors  (see below)

--------B
I have bothe pulseaudio and libraw1394 in /opt.  If I set --extra-
ldflags=/opt/lib
 the configure options  seem to be ignored  and make returns 'cannot find -
lraw1394, -lpulse etc
I even tried export LD_LIBRARY_PATH=/opt/lib beforehand with the same result



-------C
If I set a CPPFLAGS and LDFLAGS envars the  confiogure script fails to run.


 So I would be grateful if anyone on list could provide some guidance/answers 
to the following questions:-

-1) Are there  options for using external  dvdnav and dvdread  and if so how 
are they executed?
-2) Are there runtime problems in having   a preinstalled dvdnav/dvdread and 
another dedicated to mythtv?
-3) Are there options  for   setting  LD_LIBRARY_PATH for -lraw1394 -lpulse  
in other locations than /usr/lib and if so how so?
