Well, it was trying to install readline 6.0 (which is fine).  However,  
I kept getting DESTROOT errors -- which I still don't fully understand  
(I'm in the midst of reading the DEV info now).  So, I ended up  
removing all references to DESTROOT, namely the following:


post-destroot {
     delete ${destroot}${prefix}/share/info/dir

     set docdir ${prefix}/share/doc/${name}-${version}
     xinstall -d ${destroot}${docdir}/html
     xinstall -m 0644 -W ${worksrcpath} CHANGELOG CHANGES COPYING NEWS  
README \
         ${destroot}${docdir}
     eval xinstall -m 0644 [glob ${worksrcpath}/doc/*.html] \
         ${destroot}${docdir}/html
}

# Install symlinks to avoid breaking ports linked against the old  
versions
platform darwin {
     post-destroot {
         foreach f {history readline} {
             foreach v {0 1 2} {
                 ln -sf lib${f}.${milestone}.dylib ${destroot}$ 
{prefix}/lib/lib${f}.5.${v}.dylib
             }
         }
     }
}


I'm not sure what problems that will present in the future, but it got  
past the errors.  I'm still unclear as to where items such as DESTROOT  
and WORKSRCPATH are actually getting set.  Thoughts on any of this?


Thanks,
Michael
