Trying to build gtk+2

[Dwight <dcrs6000 aceweb com>]

Hi,
    So confused.
    Don't know if this is the right place/way to ask a question.

    Situation:  Trying to build firefox, thunderbird and seamonkey.
    Requirement: gtk+2
    Prerequisites: glib 2.32
    Problem: Having problems running "configure"
                     How do I tell "configure" where thing are on my system.
                     libffi, zlib, gettext, pango ... etc
    
PATH=/usr/bin:/bin:/etc:/usr/sbin:/usr/ucb:/usr/bin/X11:/sbin:/usr/vac/bin:/usr/ccs/bin:/usr/dt/bin:/usr/opt/perl5/bin:/opt/freeware/bin:/opt/freeware/sbin:/usr/local/bin:/usr/lib/instl

    Environment:  IBM AIX 5.3/6.1
    Most of the Linux stuff is in: /opt/freeware/ (Sometimes these things are linked to /usr...)
                 (libffi, zlib, gettest, pango, atk ... etc.)
    Really appreciate some help!
    Really need a new version of firefox, thunderbird and seamonkey... Old version
are not working very well these days.:-(

Thanks,
Dwight
