There are different invocations. Typical ones, like ``make configure''
take MUCH more. :-( Here is my test. Add a line
D!= echo one more >> ${.CURDIR}/count
into a Makefile of any port. Then do, say, ``make configure'' of that
port. Then --
wc -l count
23 count
23 times just to do ``make configure'' !! There are numerous ``cd
${.CURDIR} && ${MAKE} <some target>'' in the bsd.port.mk...
Even on my PII-300, there is a noticable pausing even for a simple
time make -V MASTER_SITES
0.118u 0.125s 0:00.23 100.0% 274+304k 0+0io 0pf+0w
As was noted before, the style of bsd.port.mk uses make(1) as a script
processor, for which it is poorly suited, BTW, since it was never
intended for it :( This is, probably, something we'll just have to live
with for a while, but we need to know about it...
