linux-flashplugin-6.0 not working anymore

A while ago I noticed that firefox and konqueror are not displaying flash 
applets anymore on my -CURRENT system yet it works fine on all my 6-STABLE 
machines.

When I run firefox from the shell, I get:
[nicblais_at_clk01a] ~> firefox
LoadPlugin: failed to initialize shared 
library /usr/X11R6/lib/linux-flashplugin6/libflashplayer.so 
[/usr/local/lib/pluginwrapper/flash6.so: version GLIBC_2.1 required 
by /usr/X11R6/lib/linux-flashplugin6/libflashplayer.so not defined]

(I have linux-glib2-2.4.8_1 installed)

My libmap.conf is untouched : 
# Flash6 with Mozilla/Firebird/Galeon/Epiphany/Konqueror/Kazehakase
[/usr/X11R6/lib/linux-flashplugin6/libflashplayer.so]
libpthread.so.0                 pluginwrapper/flash6.so
libdl.so.2                      pluginwrapper/flash6.so
libz.so.1                       libz.so.3
libstdc++-libc6.2-2.so.3        libstdc++.so.5
libm.so.6                       libm.so.4
libc.so.6                       pluginwrapper/flash6.so

And konqueror no longer finds my linux-flashplugin-6.0. The mplayer plugin is 
detected fine in both browsers. Since the linuxpluginwrapper port is broken 
for -CURRENT, I haven't tried to mess with it.

Am I the only one with this problem?
