Subject: 'mount -t ecryptfs ...' command refers to /bin/mount, bin/umount, etc

I noticed this a while ago but probably won't get around to fixing it, so I'm just posting a bug report.
-------------------------------------
b@ui ~$ sudo mount -t ecryptfs encrypted-dir mount-dir

There are many references  to /bin/ in the ecryptfs source code, even including  /bin/umount. for example:

-------------------------------------
b@ui ~/temp/ecryptfs-utils-111$ ag exec.*bin/
src/utils/mount.ecryptfs.c
417:            execl("/bin/mount", "mount", "-i", "--no-canonicalize", "-t", "ecryptfs", fullpath_source, fullpath_target, "-o", opts, NULL);
