gtk_init() does not return

I'm having this weird problem here.

I already installed (always compiling the src) gtk+-2.4 and Gtk2-Perl
on other machines (a Debian and a Redhat, IIRC), and it went well.

But here at home (Slackware 9.0) Gtk2 compiled fine (perl Makefile.PL
and 'make'), but 'make test' failed (at 16/34 of the first batch).
After inserting some debug printf's in xs/Gtk2.c::XS_Gtk2_init function,
I found out that gtk_init() is just not returning.
strace gave me no clue.

Have you guys seen this before?

Thanks in advance,
