Additional notes on the installation of IIPImage package on Ubuntu 12.04

I just wanted to add a note on installing IIPImage on Ubuntu 12.04.  When I tried to install the pre-requisite libraries, due to the unmet dependencies, I wasn't able to install  libfcgi0ldbl as described in the installation document.

% sudo apt-get install libfcgi0ldbl libjpeg8 libtiff4 zlib1g libstdc++6 libmemcached6

It became apparent that libfcgi0ldbl is not included in the default APT repositories in the Ubuntu 12.04 so that I had to download and install from a separate deb for this library.

Click on the download link and it should lead to the deb file you're looking for.

http://pkgs.org/ubuntu-12.04/ubuntu-universe-amd64/libfcgi0ldbl_2.4.0-8.1_amd64.deb.html#download

Lastly, it's simply running a dpkg command and install on Ubuntu.

% sudo dpkg -i libfcgi0ldbl_2.4.0-8.1_amd64.deb 

Now, you can go back to the instruction on the IIPImage package 0.9.9 on Ubuntu.
