Does locate ucs.sty (on a command line) find anything? If not, you need to install the texlive-latex-extra package (eg. via Synaptic) or simply install texlive-full.
In case you installed TeX Live from the packages of a Linux distro: Most distros split less-used LaTeX-packages into separate (Linux-distro)-packages. From the link in your question I assume that you are running Arch Linux. In this case you need to install the texlive-latexextra package which contains subfigure.sty. If you are using a different distro, the necessary package might be named differently (e.g. texlive-latex-extra in Debian/Ubuntu).
Also, as Peter notes, the subfigure package is depreciated.
