I'm trying to build the TI-GStreamer application and when i do a "make all install" i get the following error about 10 minutes into the compile

checking zlib.h usability... no
checking zlib.h presence... no
checking for zlib.h... no
configure: error: zlib.h was not found
*** You must first install zlib (libz) before you can build this package.
*** If zlib is already installed, you may need to use the CPPFLAGS
*** environment variable to specify its installed location, e.g. -I<dir>.

I've installed the latest version of ZLib and the include files are located in the same target directory that is in the Makefile.common file

Any ideas where I should be locating the ZLib files, or do I have to patch it for the ARM?
