NetBSD uses a make which is a BSD make.  Some of the differenced from GNU
make include the processing of lines like:

.include <bsd.prog.mk>

which is what your error was from.  This line included the file
/usr/share/mk/bsd.prog.mk.  With GNU make the syntax would have been
slightly different.  Other differences are in some of the wildcard
expansions.  You will want to install GNU make as 'gmake' so you can be
sure of getting the right one.

this is different.  This line would say 'look for the file called
disklabel.h in each directory in the include path so it would look for

/usr/include/disklabel.h
/usr/home/ray/installers/NetBSD/1.5/i386/1/usr/src/sys/arch/alpha/stand/installboot/../../disklabel.h

and would find neither.

the line

#include <include/disklabel.h>

will look for 


/usr/include/include/disklabel.h
and
/usr/home/ray/installers/NetBSD/1.5/i386/1/usr/src/sys/arch/alpha/stand/installboot/../../include/disklabel.h
