#64102: gettext @0.21 : build fails on tiger due to new libproc.h requirement

 Priority:  Normal     |  Milestone:
Component:  ports      |    Version:  2.7.1
 Keywords:  tiger      |       Port:  gettext
-----------------------+---------------------
 Gettext was recently updated to version 0.21. This new version requires
 libproc.h which was first available on Mac OS X 10.5 Leopard. I have
 verified that the previous version of gettext 0.20 does not require
 libproc.h and builds correctly by changing my ports tree to commit
 baf0c8bd508912bfedaf58c40dba1a402ffdf2ed.

 This is a serious issue, as on Tiger apple-gcc42 has to be compiled before
 any other packages can be, and apple-gcc42 ends up requiring gettext as a
 dependency. This completely breaks Tiger support currently in the latest
 ports tree.

 I am highly interested in fixing this, and have started this ticket to
 begin a discussion on what is best to do. I have seen other ports that
 have ran into this problem such as termux which patches the file which
 contains the libproc.h requirement with the previous version which did not
 require libproc.h. In the case of gettext, this is the file get_ppid_of.c.

 Attached is the build log with the relevant error:
