samba4: configure freezes on Checking for setproctitle_init

[barracuda156]

I tried both existing in Macports v. 4.15.5 and the latest 4.16.4 (I thought to update the port), same failure – configure reaches the following and then freezes, nothing is happening further:

Checking for library setproctitle                                     : no 
Checking for setproctitle                                             : not found 
Checking for library bsd                                              : no 
Checking for setproctitle                                             : not found

Checking for closefrom                                                : not found 
Checking for library bsd                                              : no 

Any idea what is going wrong?

Is this happening for legacy 10.5 and/or 10.6...?

I will check Leopard and SL PPC by the end of this month. Rosetta has the problem on 10.6.8. I am quite sure I never had samba4 built on either of three systems, but I don’t recall to what extent I tried.

But btw, if you remember, Ruby31 has troubles on some socket-related stuff on PPC too.

Turned out, it is broken in a similar way on i386: ​https://build.macports.org/builders/ports-10.6_i386-builder/builds/119056/steps/install-port/logs/stdio (And yeah, native ppc does not work either.)

I tried to update samba4 to current version, but configure fails early on:

Any idea what to do about it? Adding coding line to wscript does not seem to help. Python allegedly fixed this bug, but not.
