>Description:
        If libidn is installed from pkgsrc, psi won't compile.  The
        problem is that libidn installs pkg/include/stringprep.h.  psi has
        its own stringprep.h, and the -I path generated by something
        puts pkg/include before psi's own directories.  It thus gets
        inconsistent results.

        The actual results are shown in
        http://mail-index.netbsd.org/tech-pkg/2005/08/08/0007.html
>How-To-Repeat:
        cd /usr/pkgsrc/devel/libidn && make install &&
        cd /usr/pkgsrc/chat/psi && make install
>Fix:
        I changed the INCPATHS line in psi/src/Makefile; that's one bypass.
        Another is to delete libidn, and reinstall it later.
