Note: this article is no longer current as of version 0.99 of RStudio Server which no longer requires this dependency. We recommend installing RStudio Server 0.99 or later. You can download the latest version from here.
RStudio Server was linked against version 0.9.8 of OpenSSL. Since this version of OpenSSL is not available in the Debian 7 Wheezy repositories it's necessary to do a separate installation of this component prior to installing RStudio Server. This can be done as follows:
$ wget http://ftp.us.debian.org/debian/pool/main/o/openssl/libssl0.9.8_0.9.8o-4squeeze14_i386.deb $ sudo dpkg -i libssl0.9.8_0.9.8o-4squeeze14_i386.deb
$ wget http://ftp.us.debian.org/debian/pool/main/o/openssl/libssl0.9.8_0.9.8o-4squeeze14_amd64.deb $ sudo dpkg -i libssl0.9.8_0.9.8o-4squeeze14_amd64.deb
$ wget http://ftp.us.debian.org/debian/pool/main/o/openssl/libssl0.9.8_0.9.8o-4squeeze14_ia64.deb $ sudo dpkg -i libssl0.9.8_0.9.8o-4squeeze14_ia64.deb
