Install t38modem

    Goto http://www.opalvoip.org/ and download ptlib-2.6.7 and opal-3.6.8 from SourceForge
    untar the packages
    set the default lib search path with 'export LD_LIBRARY_PATH=/opt/opal/lib:/opt/ptlib/lib'
    set the location of the ptlib source code with 'export PTLIBDIR=<path to ptlib source>'
    first compile ptlib with './configure --prefix /opt/ptlib; make; make install'
    set the location of the opal source code with 'export OPALDIR=<path to opal source>'
    then compile opal with './configure --prefix /opt/opal; make; make install'
    download t38modem-1.2.0 from http://sourceforge.net/projects/t38modem/
    compile t38modem with 'make USE_OPAL=1 opt'
    copy t38modem from obj_linux_x86_opal to /usr/local/bin
    to fix libraries run 'patchelf --set-rpath /opt/opal/lib:/opt/ptlib/lib t38modem'

I could not get things to work with t38modem 3.6.8. So please download v2.0.0 including the accompanying opal branch.
