Comment:

 I've updated pstree to 2.39 in r137283, but I haven't made all the changes
 you proposed, because many of them are regressions.

 For example, pstree does not install any libraries, and it correctly
 indicates this via the line `installs_libs no`, but your patch removes
 this line. There are no ports that depend on pstree, so it doesn't really
 affect anything, but since the port maintainer has already gone out of his
 way to indicate that the port does not install libraries, there's no
 reason to remove this indication.

 The existing configure script records the values of the CC, CFLAGS and
 LDFLAGS variables into the Makefile and uses them at build time, which
 means it's UsingTheRightCompiler and `-arch` flags. Your proposed change
 doesn't do any of this, so a wrong compiler might be used, and the build
 will always use the compiler's default architecture even if the user
 requested something different.

 The README should still be installed, even if there is also a manpage.

 I did apply some of your other changes: r137280 r137281

 I also made some additional changes of my own: r137279 r137282
