I'm not sure if everyone's aware of this (I wasn't), but an
empty colon in your PATH is an implicit . (!!)

i.e. PATH=/bin:/usr/bin:/usr/local/bin:

In sh(1):

     2.   The shell searches each entry in PATH in turn for the command.  The
          value of the PATH variable should be a series of entries separated
          by colons.  Each entry consists of a directory name.  The current
          directory may be indicated implicitly by an empty directory name, or
          explicitly by a single period.

Regards,

Leon.
