OS specific notes

Ubuntu 10.04

• install tcl8.5 and tcl8.5-dev (apt-get and friends)
• download environment-modules and configure/make/sudo make install

After this (with a working g++), the demo procedure pretty much worked out of the box (except for a minor issue with a Python module loading, but that's beside the point).

Ubuntu 11.10

• install Tcl and environment-modules:
• sudo apt-get install tcl8.5-dev
• download environment-modules and configure/make/sudo make install
• add default install path to PATH

export PATH=/usr/local/Modules/3.2.9/bin:$PATH

• install g++ (only gcc is installed by default)

sudo apt-get install g++

• install 32-bit libc:
• fixes missing bits/predefs.h error message

sudo apt-get install libc6-dev-i386

• adjust LIBRARY_PATH to fix /usr/bin/ld: cannot find crti.o: No such file or directory

export LIBRARY_PATH=/usr/lib/x86_64-linux-gnu

• this (maybe) also needs to set when using the built GCC compilers

Arch Linux

• install Tcl, Python 2.x and make:

pacman -S tcl python2 make

• download and configure/make/make install environment-modules

OSX 10.7.4

• Tcl is installed, but you may have to disable X when building the environment-modules (configure --without-x)
• can build GCC,OpenMPI and Lapack but fails to build ATLAS
