I see you're running Solaris.
The Solaris version of the 'patch' program is extremely buggy.
If the 'make test' command fails with a message

  patch: Line must begin with '+ ', '  ', or '! '.

you must install a better version of 'patch', for example, GNU patch.

The default location for temporary files ($TMPDIR) does not
exist, or is not accessible.
You must use environment variable TMPDIR or TEMP to designate a writable
directory to hold temporary files.
