php 4.0.6 & SCO: intallation nitemare.. as usual. Please help?

<rant> why o why each and every new installment of php has to take 2 to 5 days to get up and running on a SCO box ? Maybe i'm just plain brain-dead... i went thru the compilation cycle for versions 4.0.3, 4.0.4 and 4.0.6, and still it is so damn hard! (maybe I'm just about the only one that still has to cope with that kind of platform...) I don't like to play with automake+autoconf, but even if I try to run buildconf I get into trouble: - ./build/buildcheck.sh relies on the 'which' command, that is absent from SCO Openserv 5.0.5 (even though I installed all of the GNU stuff that comes pre-packages from sco skunkware and a great deal more from source). Similar command is aptly named 'type', which under linux serves an entirely different purpose... The .mk files generated by configure are not accepted by make (GNU make 3.78.1) since build rules lines start with 2 spaces instead of a nice tab char! The sockets.c file will refuse to compile, since constant h_errno is not defined (NB: the version of the SCO developement environment I use is quite old: 5.0.1A; in version 5.1.1A this is probably not true anymore). The pthreads lib () will be reported not found because when it's checked for (line 2662 of the stock configure) it misses a -lsocket... Any help / suggestion would be greatly appreciated! Thanks, Gaetano </rant>
