Comment (by ryandesign at macports.org):

 I applied the patch in r33914. But I would still like to see another patch
 to remove the use of "system" for making symlinks. We have a tcl procedure
 "ln" to make symlinks so it should not be necessary to call out to
 "system" for this. For example instead of

 {{{
 system "cd  ${destroot}${prefix}/lib;ln -s ${lib} ${liblink}"
 }}}

 it should be

 {{{
 ln -s ${lib} ${destroot}${prefix}/lib/${liblink}
 }}}
