Addendum to the original README: relevant details to get it work on Mac OS X Leopard

Vidit Jain <vidit@cs.umass.edu>

Please read the original README before proceeding.

While most of the details included in this document are specific to Mac OS X, they may
also be helpful in resolving similar issues on other platforms.

Required libraries/binaries:
---------------------------
* libjpeg : fink distribution available
* gfortran : no fink distribution available. Can use the version available at
             http://hpc.sourceforge.net/.
	     Note: g95 fortran compiler fails to compile the source in trlan
		   directory.
* lapack, blas

Modifications to source files
-----------------------------
1) values.h : This interface is obsolete and may not be present on all flavors
	of Unix (Mac OS X does not have it). This header file is mostly needed 
	for obtaining the system-dependent max-, min-, and similar values for
	different data types such as float and int. Although some of the 
	required constants are defined in util/types.hh, <float.h> is needed 
	for resolving  macros such as FLT_MAX. 

Files affected : util/kmeans.cc, util/segmentation.cc, group/texture.cc

2) Some distributions of Unix may not have 'uint' data-type defined.
Util::uint is type-defined as 'unsigned int' in this distribution.
This name resolution need to be made explicit by using one of the two following
ways depending on the required name resolution scope: 
    - Using Util::uint
    - uint 'replace by' Util::unit

Files affected: util/configure.cc, apps/unitex.cc

3) For reasons similar to (1) and (2), "malloc.h" need to be replaced by
"stdlib.h"  in bench/csa-1.2/csa/prec_costs/{main.c, parse.c}

Modifications to Makefile
-------------------------
1) Makefile.gcc : need to include the appropriate directories for libjpeg
	in ${IFLAGS} and ${LFLAGS}
2) trlab/Makefile.gcc : need 'ranlib libtran.a' after creating the library
	archive libtrlan.a, i.e., after 'ar -cru libtrlan.a ...'


Happy segmenting!!!
