 I have a couple problems with the "create symlinks" part of the pre-build
 phase of the lilypond portfile. It reads:

 {{{
             # create symlinks
     if { [file exists "/usr/lib/libguile-srfi-srfi-1-v-3.so"] == 0 } \
         { ln -s ${prefix}/lib/libguile-srfi-srfi-1-v-3.so /usr/lib
 /libguile-srfi-srfi-1-v-3.so }
     if { [file exists "${prefix}/lib/libguile-srfi-srfi-1-v-3.so"] == 0 }
 \
         { ln -s ${prefix}/lib/libguile-srfi-srfi-1-v-3.dylib ${prefix}/lib
 /libguile-srfi-srfi-1-v-3.so }
 }}}

 This code seems to create a symlink in /usr/lib and ${prefix}/lib. A port
 should not do the former because it is outside of ${prefix}. And in both
 cases, the symlink is being created outside ${destroot} and is thus not
 registered to the port. Why are these symlinks needed by this software,
 and is there any other way the same goal could be accomplished without
 writing files outside the destroot?
