Thanks for the prompt replies, everyone.
Are you always this way, or was I just lucky? ;-)
I made a test Makefile that set variables to the values of various flags
on the uname command. I'm definitely still 'green'. I had to use the
'make -n' mode to see the variable assignments without make trying to do
something unknown to me. But, emboldened with that interesting output, I
attempted to write a 'simple' test Makefile that when read by make would
unzip one file if found to be running under the OS version of FC5...
failing that, unzip a different file.
To further demonstrate my novice status on all things 'make', observe my
lame test file, whose results are not-what-i-expect-or-wanted.

test:
osver := $(shell uname -r)
#osname := $(shell uname -s)
#cpuarch := $(shell uname -m)
#youname := $(shell uname -o)
ifeq ($(osver),2.6.15-1.2054_FC5)
unzip ksh.zip
else
unzip ksh2.zip
endif

I obviously haven't "caught on" yet.
Lifesavers welcome.
Thanks
