I'm trying to get x11-fm/sushi and mail/evolution to build on FreeBSD 8.
I've applied the patch from
<https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=196031>; to build
www/webkit-gtk3 with gcc and libstdc++ from ports.  When I try to build
either sushi or evolution, I get errors like this:

Makefile:672: recipe for target 'sushi-start' failed

My suspicion is that this is caused by using binutils from base instead
of the newer version from ports.  I tried getting around this by
applying a big hammer and adding USES=compiler:c++11-lib to the Makefile
and got this error:

  GISCAN   Sushi-1.0.gir

The problem now appears to be that the older version of libstdc++ from
base is being used instead of the newer version from the gcc port.  That
his happening because -L/usr/local/lib/gcc48 is not present in the
linker flags.  The proper value of LDFLAGS is getting passed to
configure via CONFIGURE_ENV.  From config.log:

ac_cv_env_LDFLAGS_set=set
ac_cv_env_LDFLAGS_value=' -L/usr/local/lib -Wl,-rpath=/usr/local/lib/gcc48 -L/us
r/local/lib/gcc48'

Unfortunately configure ends up ignoring it and using pkgconf to
generate the linker command line:

pkg_cv_SUSHI_LIBS='-lfreetype -lgirepository-1.0 -lgjs -lclutter-gtk-1.0 -lclutt
er-gst-2.0 -lclutter-1.0 -lcogl-path -lcogl-pango -lcogl -lgmodule-2.0 -lEGL -lX

What is the proper way to fix this?  Should the .pc file for webkit-gtk3
record the extra library path because it was compiled with gcc from
ports?  Should configure concatenate the value of $LDFLAGS with the
output of pkgconf?
