Well, it will "configure", but afterwards you need `make` and `make install`. If you are not the root user, you will likely prefer to install it in your own home directory with options like:

$ ./configure --prefix=$HOME/local/openmpi-1.4.3
$ make
$ make install

Any reason not to use the latest version?
