[Trisquel-users] Where is abrowser 31 for 64bit?

[mtlben]

My 32bit machines received the abrowser 31 update a couple of days ago, but I  
was surprised to see that my 64bit machines stayed with version 30.  Now I  
see by looking at the following page that the update doesn't seem to exist  
(yet) for amd64: http://packages.trisquel.info/toutatis-updates/web/

Is this some bug in the build process, or building the amd64 version requires  
some special treatment?
