Well, you can do a git clone to get that file.  Or browse the git
repository at http://maxima.git.sourceforge.net/git/gitweb-index.cgi.

Oh.  Hmm.  It looks like maxima doesn't have an inverse for erfi, but it
does have an inverse_erf function.  That will give you the inverse_erfi
function if you want numerical values.
