build error when compiling ark libzip plugin

[Orville Bennett]

I had some trouble when enabling zip support in ark. Reason seems to  
be "off_t" defined in
both /usr/include/sys/types.h and kdeutils-4.2.0/ark/plugins/ 
libzipplugin/zipplugin.cpp.

zipplugin.cpp block
#ifdef LIBZIP_COMPILED_WITH_32BIT_OFF_T
#define __off_t_defined
typedef quint32 off_t;
#endif /* LIBZIP_COMPILED_WITH_32BIT_OFF_T */

types.h block
#ifndef _OFF_T
typedef __darwin_off_t		off_t;
#define _OFF_T
#endif

This thread convinced me the definition in zipplugin.cpp was  
unnecessary http://lists.apple.com/archives/Scitech/2006/Sep/msg00071.html
which lead to this change in kdeutils-4.2.0/ark/plugins/libzipplugin/ 
CMakeLists.txt

Was that too wordy? I think so.
