Comment(by anatol.pomozov@…):

 > It would be better if there was a tarball we could fetch rather than
 checking out a git tag.
 The sources can be download as a file.
 https://github.com/fuse4x/kext/downloads

 I was not sure how to do it in the Portfile. It requires 'master site' and
 I did not find an example with github as a master site.

 If you can take care of it would be great.

 > Does the kext need to be installed into /System/Library/Extensions?
 Yes. In case if the kext is located here - kexload tool can load the kext
 without the root password. Fuse starts this kext only when it mounts any
 fuse filesystem first time.

 Theoretically it is possible to start fuse4x at the boot-time.
 http://guide.macports.org/#development.examples.startupitem It means that
 libfuse should not even try to load the kext by itself as we assume kext
 is loaded all the time.
