problem with libgdk-x11-2.0.so.0

[Claude Baudouin]

Hello,

I work with  PC-BSD(FreeBSD Version : 6.0-RELEASE, Machine : i386)  and after 
installation of /usr/ports/french/acroread here is that I get:
$ acroread7-fr &
$ /usr/local/lib/fr-acroread/usr/local/Adobe/Acrobat7.0/Reader/intellinux/bin/acroread: 
relocation error: /usr/lib/libgdk-x11-2.0.so.0: undefined symbol: 
g_get_application_name
$
linux_base-8-8.0_6  Base set of packages needed in Linux mode (only for i386)
and linux_base-rh-7.3   Basic packages for Linux mode from Red Hat 7.3/i386 
are installed.
What is the problem with this library?
thank in anticipation,
Claude
