XEmacs 21.4.6 & VHDL Mode

Hi, I've just downloaded xemacs v21.4.6 from http://ftp.ru.xemacs.org/pub/xemacs/binaries/win32/installshield/ running on windows2000. I was previously using v21.1.9 and had vhdl-mode installed and running with no problems. When I now load a .vhd file I see the following message displayed by xemacs, and the vhdl support is not available: File mode specification error: (invalid-byte-code "variable reference to constant symbol :prefix") Is there an issue with v21.4.6 or am I just not doing it right? Cheers, Vince.
