Comment 11 for bug 311029

Here are Martin Lindhe's instructions from post #3 above, updated for 10.04, again assuming you are using 64-bit Ubuntu. The resulting curl installation works just as the curl mapage says it should, against an OpenSSL server.

==========
#the line below will create a temporary directory and move you to it - so that you can easily clean up the build files later
# you are short on disk space
mkdir -p ~/temp/curl
cd ~/temp/curl

sudo apt-get install build-essential debhelper libssh2-1-dev
sudo apt-get source libcurl3
sudo apt-get build-dep libcurl3

cd curl-7.19.7/debian

gedit rules

   find and replace "--without-libssh2" with "--with-libssh2"

cd ..

sudo dpkg-buildpackage

cd ..

sudo dpkg -i curl_7.19.7-1ubuntu1_amd64.deb
sudo dpkg -i libcurl3_7.19.7-1ubuntu1_amd64.deb
sudo dpkg -i libcurl3-gnutls_7.19.7-1ubuntu1_amd64.deb

#at this point you may move away from, and then remove the entire ~/temp/curl directory if you wish
# alternately, you may choose just to keep the 3 .deb files which were the end product of the building,
# in case you have to use them again in the future.
