OpenVRML plugin in extras buggy?

Hi,

I just noticed that there is openvrml in FE6.
I quickly installed both the i386 and x86_64 packages
but it doesn't appear on the about:plugins page in Firefox,
no matter which version (32 or 64 bit) I try to run.

There's no openvrml in FE6 bugzilla, so I report it here.

# yum list "openvrml*"
Installed Packages

I noticed this (same for the 64-bit lib):

       librt.so.1 => /lib/librt.so.1 (0xf6eeb000)

and I have put these lines into the /usr/bin/firefox script:

LD_LIBRARY_PATH="$MOZ_DIST_BIN"
export LD_LIBRARY_PATH

but no success.

On the other hand, when I try to compile openvrml-0.16.1
(which is a virtue in itself, as compilation requires 1.6+ GB(!)
on some source files) it announces itself correctly under Firefox.

Is there a known fix for this?
