  Thank you, but nothing work.
1. The orafce from www.pgfoundry.org doesn't pass the make step, is
looking for some files  that doesn't exist, see below:
    orafce : make
    Makefile:16: ../../src/Makefile.global: No such file or directory
    Makefile:17: /contrib/contrib-global.mk: No such file or directory
    make: *** No rule to make target `/contrib/contrib-global.mk'.  Stop.

2. ora2pg, looks like something that extract DB schemes from a running
oracle DB, but I have not ORACLE running. I just have old ORACLE/SQL
sources that I need parser to SQL or PostgSQL.

3. About the ambitious project "protopg", I success to compile this
projects but the parser fall. The parse have a problem with a word
"CONSTRAINT", see below:
    protopg-20060905 : ./ora_parser < tes.sql
    -- syntax error, unexpected "CONSTRAINT", expecting ORA_ID on line 6 --

    -- BEGIN OF UNRECOGNIZED STATEMENT
    CREATE TABLE v5templates . cmt_items ( item_id NUMBER ( 7 ) ,
template_id NUMBER ( 7 ) , page_title VARCHAR2 (     100 ) , CONSTRAINT
pk_cmt PRIMARY KEY ( item_id ) ) ;
    -- END OF UNRECOGNIZED STATEMENT

I will try debug it, or maybe send a mail to the developer/contacts.

 Any way, thank very much, Gustavo
