[FFmpeg-user] Configure says it can't find openssl

I run the following configure script using the latest ffmpeg pulled from

./configure --disable-decoders --disable-encoders --enable-decoder=h264
--enable-decoder=vc1 --enable-decoder=aac --disable-ffplay
--disable-ffprobe --enable-openssl

It's on an embedded system, hence disabling most of the features.
It returns with
ERROR: openssl not found

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user at ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "ffbuild/config.log" produced by configure as this
will help
solve the problem.

The log file is attached.

I have made sure that openssl is installed
opkg list-installed | grep openssl
openssl - 1.0.1p-r0.0
openssl-conf - 1.0.1p-r0.0
openssl-dbg - 1.0.1p-r0.0
openssl-dev - 1.0.1p-r0.0

Any help greatly appreciated.
