The CVS history for www/php4/patches/patch-al, which adds the "-n",
says:

    completely ignore system php.ini for all pear-related operations;
    this is necessary to avoid being subject to e.g. open_basedir or
    safe_mode settings

I'm guessing that this is because jdolocek didn't want any user settings
to affect the installation of various PEAR modules by the php4 package.
However, in your case, this causes the php_gd.so to not be loaded, which
is apparently needed by the Image_Color PEAR module.

I think you should submit a PR about this.  I think pkgsrc should
really somehow use its own php.ini file for module installation if it
wants to insulate itself from users' custom php.ini settings.
