Send Bug Report unable to send bug report

[Järneström Jonas]

In GNU Emacs 20.7.1 (sparc-sun-solaris2.8, X toolkit)
 of Tue Jan 16 2001 on sunray8.era-a.ericsson.se
configured using `configure  --prefix=/usr/bag/emacs/20.7
--datadir=/usr/bag/emacs/share'

My system recently switched to Solaris 2.8.
This had the effect that mail mode is no longer able to find the
sendmail program, which it expects to find at /usr/sbin/
instead of eg /usr/lib/ where I can see a copy.

A side effect of this is of course that the "Send Bug Report" command
is broken.

Has my unix system been tweaked in a non-standard way or is this an
emacs problem? Besides including above path in my path, is there
anything simpler I could do?
