It's ugly:

v=byte(!VERSION.RELEASE) & v=v[where(v ge 48 and v le 57)]
v=float(string(v[0]))+float('.'+string(v[1:*]))

if v lt 5.4 then message, "IDL v5.4 required"

This is to get around release names like '5.3.2a' or some such. I you
are sure you just want 5.4 you can of course do the much cleaner

if !VERSION.RELEASE eq '5.4' ...
