install returns success exit status even when wmake command not found

If user forgets to run . /opt/openfoam222/etc/bashrc, then the two separate packages are installed and user would assume that everything is properly installed although some of the required software (for the INTERNAL wrapper) was not built.

There is a printed message (_./install_foam_interface.sh: line 5: wmake: command not found_) but can be easily overlooked as the later messages suggest that everything worked. Also the exit status also is 0 which is misleading.
