895	Multiply-defined libraries on Mac OS X dylib compilation	Michael Wood-Vasey	eugene	"Mac OS X dylib is pretty picky about building the dylib libraries with no duplicated/conflicting names.  I present the following fix to the problem I outline further below.

I think I've tracked down the issue and solution for the multiply-defined _DVOTableFormat and _DVOTableMode.  These two things are 'enum's defined in 'dvo.h' ('Ohana/src/libdvo/include/dvo.h') which is included by 'kapa.h' which is included in a few of the files in 'psphot/src' ('psphotRadialPlot.c', 'psphotSummaryPlots.c', 'psphotVersion.c').  I changed lines 17 & 20 in 'dvo.h' to put in an 'extern' in front of the two enum definitions and then 'make clean' in Ohana and in 'psphot' and 'psconfigure; make; make install'.

The problem

I've run into the following problem in IPP 2.2 in combining libraries into .dylib files in Mac OS X.
