Pdflatex

During yet another LaTeX project on my MacBook, I added some algorithms to my paper. After checking a couple of examples online, and discussing with a colleage I decided to go with algorithm2e over others such as algorithm, algorithmic, algorithmicx, program and pseudocode[1].

However I got the following error “! LaTeX Error: File `algorithm2e.sty’ not found.” Since I am using macport, to resolve this I needed to install the texlive-science package by executing sudo port install texlive-science, and all was good again.

When working on a recent paper for a conference, I was required to produce it using the Spring Lecture Notes in Computer Science (LNCS) style. Being naive, I assumed TeX would automatically download the required package… unfortunately I got the following error “LaTeX Error: File `llncs.cls’ not found.” So I had to install the class manually. Here are the instructions for installing it on Mac OS X for latex from macport.
