Here is the configure script:

./configure \
--enable-debug \
--with-wmsclient \
--with-tiff \
--with-jpeg=/usr/local/src/jpeg-6b \
--with-png=/usr/local/src/libpng-1.2.2 \
--with-gd=/usr/local/src/gd-2.0.7 \
--with-freetype=/usr/bin/freetype-config \
--with-zlib=/usr/local/src/zlib-1.1.4 \
--with-proj=/usr/local/src/proj-4.4.5 \
--with-postgis=/usr/local/pgsql/bin/pg_config \
--disable-rxposix-conflict-error \
--with-php=/usr/local/src/php-4.2.3

Looks like there might be some funky stuff happening when running ./configure,
like maybe when it recognizes libwww it automatically enables WMS client
support?  See partial output:

This should be addressed at the same time as replacing libwww in bug 237

This has been fixed somewhere between 3.7 and 4.3.

I have verified that in V4.3, if you request --with-wmsclient and fail to
include GDAL and OGR, then you do not get this linker error any more. WMS client
won't support raster reprojection and may not be very useful in this context,
but it can work.
