nppdf.so: undefined symbol "__ctype_b_loc"

[Xiao-Yong Jin]

Hi all, after upgrading firefox and acroread, I got this when I tried
to use the plugin,

LoadPlugin: failed to initialize shared library /usr/X11R6/Adobe/Acrobat7.0/ENU/Browser/intellinux/nppdf.so [/usr/X11R6/Adobe/Acrobat7.0/ENU/Browser/intellinux/nppdf.so: Undefined symbol "__ctype_b_loc"]

I have these lines in my /etc/libmap.conf,

# Acrobat7 with Mozilla/Firebird/Galeon/Epiphany/Konqueror/Kazehakase
[/usr/X11R6/Adobe/Acrobat7.0/ENU/Browser/intellinux/nppdf.so]
libc.so.6                       pluginwrapper/acrobat.so

Bug?  Or my configuration fault?
