whoami may not be in PATH in updatedb (4.1.5)

[Will Partain]

(Probably known, but I'll mention it anyway...)

Line 93 or so of updatedb in 4.1.5 is

PATH=/bin:/usr/bin:${BINDIR}; export PATH

The script goes on to backtick `whoami`, which ends up 'not
found' on at least Solaris systems.  The simplest fix seems
to be to change the line to:

PATH=/bin:/usr/bin:${BINDIR}:/usr/ucb; export PATH

Keep up the good work,

Will
