ERLang Compiling

I copied mod_shared_roster_ldap.erl, and mod_logmnesia.erl into the C:\Program Files\ejabberd-1.1.3\bin directory and attempted to compile them.
When I try to compile 2 add-ons to ejabberd it gives me the following errors:

With mod_shared_roster_ldap.erl, it gives me
;2> c(mod_shared_roster_ldap.erl).
;./mod_shared_roster_ldap.erl:none: internal error in parse_module;
;crash reason: {undef,[{epp,parse_file,
; ["./mod_shared_roster_ldap.erl",[".","."],[]]},
; {compile,parse_module,1},
; {compile,'-internal_comp/4-anonymous-1-',2},
; {compile,fold_comp,3},
; {compile,internal_comp,4},
; {compile,internal,3}]}
;error

With mod_logmnesia.erl it gives me almost the same thing
;4> c(mod_logmnesia.erl).
;./mod_logmnesia.erl:none: internal error in parse_module;
;crash reason: {undef,[{epp,parse_file,["./mod_logmnesia.erl",[".","."],[]]},
; {compile,parse_module,1},
; {compile,'-internal_comp/4-anonymous-1-',2},
; {compile,fold_comp,3},
; {compile,internal_comp,4},
; {compile,internal,3}]}
;error

I have a base install on ejabberd 1.1.3_1 on Windows XP SP2. This is just a test box; it will be deployed to a more permanent spot once I can prove it will work. It will be deployed to roughly 3000 employees thought western Canada.

Thanks
