Comment (by caverac):

 I am sorry that this is taking so long, really appreciate the time you're
 putting in this. This is what I did

 1. In the configure file of upc

 {{{
 LIBS="${_isl_saved_LIBS} -lisl.14"
 }}}

 2. In the Portfile of upc

 {{{
 path:lib/pkgconfig/isl.pc:isl14
 (...)
 --with-isl=/opt/local/libexec/isl14
 (...)
 post-extract {
     xinstall -d -m 0755 ${build.dir}/gcc
     ln -s ${prefix}/libexec/isl14/include/isl ${build.dir}/gcc
 }
 }}}

 3. Installed and got the same error.

 4. Went back to see the configure file, but the line I changed in the
 first step went back to

 {{{
 LIBS="${_isl_saved_LIBS} -lisl"
 }}}

 If this file is build with autoconfig, any change that I make on it, will
 revert back when I try to install again, doesn't it?
