failure during attempted build of zsh 3.1.1

[lvirden@xxxxxxx (Larry W. Virden, x2487)]

While trying to build zsh 3.1.1 on my Solaris 2.5.1 SPARC, I get this
error:

Updated `paths.yo'.

I don't know what to do to resolve this problem.  I checked Etc/BUGS and
Etc/FAQ and see no reference to resolving this.
