why did you install the executables in your /home directory?
I think the /usr/local path for such an installation would be the better solution.
Anyway, edit your .bashrc (within your homedirectory) and add a line
be sure to read the manpage for the shell bash in order to learn about under which circumstances the .bashrc file is sourced! There are different profilefiles for different distributions. The default is that ~/.profile is sourced if bash is invoked as a login-shell and ~/.bashrc if it's not. So you may add the new path to your .profile as well.
