Hi Mike,

The offending code in configure.in is:

if test "$with_gd" !=3D no; then
  AC_PATH_PROG([GDLIB_CONFIG], [gdlib-config])
  if test -n "$GDLIB_CONFIG"; then
    libgd_CPPFLAGS=3D`gdlib-config --cflags`
    libgd_LDFLAGS=3D`gdlib-config --ldflags`
  elif test -d "$with_gd"; then
    libgd_CPPFLAGS=3D"-I$with_gd/include"
    libgd_LDFLAGS=3D"-L$with_gd/lib"
  fi
(...)
fi

So what you gave to --with-gd is only used if gdlib-config cannot be=20
found in your $PATH. And then it doesn't even try to use the=20
gdlib-config in the custom path that you provided, but just appends=20
'include' and 'libs' to it. This could indeed be improved.
