I've looked a bit into this, but I've only a partial fix.
For one thing, ILISP tries to compile and load the INIT lisp-files,
e.g. ilisp-pkg.lisp and cl-ilisp.lisp on startup.
This fails, because ECL has SPECIAL-FORM-P in the COMMON-LISP package,
but this has been superseded by SPECIAL-OPERATOR-P (ANSI).
ILISP tries to cope with that, by defining its own SPECIAL-FORM-P
function (for backwards compatibility), but fails, because this
conflicts with ECL's built-in function.
You can reproduce this by simply compiling cl-ilisp.lisp 
(after _loading_ ilisp-pkg.lisp).
Additionally, there was a problem with the file-extensions.
I've attached a fix for all that, such that I'm able to run ILISP with
ECL now, but it's not a *real* fix, since it requires some manual
work: you have to _load_ ilisp-pkg.lisp into ECL, compile it, and
compile cl-ilisp.lisp after that, as well (these files are in the
ILISP directory, of course :)
After that, starting ILISP+ECL should work fine.

Doing all this more cleanly would probably involve removing
SPECIAL-FORM-P from ECL, IMHO.
Unfortunately I don't have time to debug this further right now,
but I'll try to look into this again, perhaps next week ...

You should probably get the latest CVS-version from Sourceforge.
This worked for me.
