Introducing OpenCOBOL

OpenCOBOL is an open source COBOL compiler.
OpenCOBOL implements a substantial part of the COBOL 85 and COBOL 2002 standards, as well as many extensions of the existent COBOL compilers.
Removed unnecessary environment flags, referenced bug report for option in configure script.

Use #{info} instead of specifying path
Use formulas to reference berkeley-db4 and gmp
