>Description:
Building the "rtorrent" package fails under Mac OS X:

=> Required installed package libtool-base>=1.5.18nb5: libtool-base-1.5.22nb4 
found
=> Required installed package pkg-config>=0.19: pkg-config-0.21 found
=> Required installed package libtorrent>=0.10.0: libtorrent-0.10.4 found

===> Patching for rtorrent-0.6.4nb1

===> Creating toolchain wrappers for rtorrent-0.6.4nb1
ERROR: libidn is not installed; can't buildlink files.
*** Error code 1

Stop.
bmake: stopped in /usr/pkgsrc/net/rtorrent
*** Error code 1

The reason is that "pkgsrc/www/curl/builtin.mk" decides to use the
"libcurl" provided by Mac OS X. "pkgsrc/www/curl/buildlink3.mk" will
later include "devel/libidn/buildlink3.mk" unconditionally. "libidn"
is however not available under Mac OS X.

>How-To-Repeat:
cd pkgsrc/net/rtorrent
bmake

>Fix:
Removing "pkgsrc/www/curl/buitlin.mk" fixes the build problem.
