The actual result is:
$ jhbuild shell
$ ptlib-config --prefix
/home/gnomeslave/gnome/work/bin

but if i force it to be /home/gnomeslave/gnome/work/bin/lib (by passing
this path to configure script) then it does not find the header files:

$ ./configure --enable-maintainer-mode
--prefix /home/gnomeslave/gnome/work/bin
--with-pwlib-dir=/home/gnomeslave/gnome/work/bin/lib
...
checking
for /home/gnomeslave/gnome/work/bin/lib/include/ptlib/pprocess.h... no
configure: error: You need the PWLib headers to compile Ekiga

I've alse seen taht libpt.so is actually installed here:
/home/gnomeslave/gnome/work/bin/lib/libpt.so

so looks like the path given by ptlib-config --prefix is ok.

Looks like Opal has some fallback in its configure.ac file:
...
dnl look for ptlib, use a preference order of explicit PWLIBDIR,
directory
dnl at same level, home directory, /usr/local or /usr.
...
