build log

Hi, I'm a MacPorts developer trying to update our samba4 port to 4.14.2. After working around the problem I reported in #14680, the build still fails on macOS 10.13.6 due to struct mntent / setmntent / getmntent / endmntent not existing.

The configuration phase correctly identifies that there is none of this "mnt" stuff:


Checking for header mntent.h                             : no 

Checking for endmntent                                                            : not found 

Checking for getmntent                                                            : not found 

Checking for setmntent                                                            : not found 


Yet the build phase still tries to use it, which fails:
