No, I actually made that up myself, based on the documentation. The manual
mentions [1] that extract.post is a good place to "generate a configure
script out of an autotoolized configure.ac file for example", so that's
what I tried. Also the manual does not document any default rule when
extract.post is omitted (whereas it does so for other stages). So I didn't
know that I had to call world/patchin/post from my custom extract.post rule.

Actually the mediastreamer2 package comes with its own autogen.sh script.
That's why I am running

cd $(MEDIASTREAMER2_DIR) && [ -f configure ] || sh autogen.sh

Is that correct? I guess that if there's an autogen.sh script in the
package, that should normally be used in preference to the generic ptxdist
version. Right?

Thanks,

Guillermo
