We should be compiling sshfs instead of shipping a pre-compiled version, that IIRC came out of OSXFuse. @stewiem2000 already has some code to do this, so perhaps that would be the way to go.
For sshfs, what always worked well for me was to simply use the one from the OSXFuse website (sshfs 2.5.0). I am simply replacing the file sshfs-static in the plugin with a symlink to /usr/local/bin/sshfs.
