Reading this I've 'see the light'. I remembered that while 'perl Makefile.PL',
at Gtk2, it throws out this message:

Unrecognized argument in LIBS ignored: '-Wl,--export-dynamic'

"Hm, wait. Export dynamic... That's interesting." So I've tried compiling Gtk2
module without it, again. And tests hanged on Gtk2->init, as before.

OTOH, when I've placed this options on Makefile, tests worked! 

Hmm.. oops, not everything:

t/13.GtkTooltips..........ok                                                 
t/14.GtkToolbar...........ok 3/23

Freezes here now. But it's much better than before.

The whole Slackware site it's very unmantained, but Slackware user groups are
good resources of information. Unfortunatelly, I only know GUS-BR, which is
mostly in Portuguese.

As a Slackware user, I'm used to rebuild things. :^)

I've rebuild perl5 at another machine (this one) some time ago (perl 5.8.1-rc3),
but hadn't test it with Gtk2. I tried it, and all tests worked (even Toolbar
that hang'd with 5.8.0).

The good news is that I would rebuild perl anyway at there machines, for speed
and memory footprint[1] reasons. And, also, to enable features.

Well, thanks for the help folks, and long life for Gtk2. :-)

Best regards.

-----------
[1] Last time I built perl5 (5.8.1-rc3) using shared libraries i've got an
20kb-sized /usr/bin/perl5. The library (libperl.so) got 1.2M, but that's shared
anyway..).
