[SLUG] enigmail problem

[Heracles <heracles@xxxxxxxxxxxxxx>]

I have enigmail working perfectly on my 32bit version of Ubuntu 8.04. I 
wish to get it working on my 64 bit version and import the keys I use. I 
have used the same user so that Thunderbird and enigmail use the same 
config files but when I get an encrypted email I get the error message

"Enigmail: Enigmime service not available. Either fix the problem or 
uninstall enigmail..."

Is enigmail available for x86_64?

Any help appreciated
