unable to build mplayerplug-n 3.55 on Debian Squeeze (amd64 dual-core)

On running configure (as normal user) with the gecko-sdk path AND exporting PATH with the
directories inside geck-sdk (won't run xpidl without path set) I get the following:

/usr/local/src/gecko-sdk/bin/xpidl -w -m header -I  -I Source -e Source/nsIScrip                                                                                     tableMplayerPlugin.h Source/nsIScriptableMplayerPlugin.idl
/usr/local/src/gecko-sdk/bin/xpidl: error while loading shared libraries: libgli                                                                                     b-1.2.so.0: cannot open shared object file: No such file or directory
p

libglib-1.2.so.0 IS in  /usr/lib, so I am perplexed.
Its as if xpidl is not looking in PATH at all, so where IS it looking?
Does anyone have a useful suggestion? If so please tell me.
Thanks.
