#72433: libbind 6.0: missing dependency on groff
---------------------+---------------------
 Reporter:  bictorv  |      Owner:  (none)

 Priority:  Normal   |  Milestone:
Component:  ports    |    Version:  2.10.6
 Keywords:           |       Port:  libbind
---------------------+---------------------
 In macOS 15.4.1, the installation of libbind fails when generating the
 documentation, at the stage "Staging libbind into destroot". with the
 message {{{Error: Failed to destroot libbind: command execution failed}}}.
 Checking the log file, I find
 {{{
 :info:destroot gethostbyname.man3 -> gethostbyname.cat3
 :info:destroot /bin/sh: -c: line 0: syntax error near unexpected token `|'
 :info:destroot /bin/sh: -c: line 0: `(  |  -mandoc ) <gethostbyname.man3
 >gethostbyname.cat3'
 :info:destroot make[1]: *** [gethostbyname.cat3] Error 2
 }}}
 and checking the libbind/work/libbind-6.0/doc/Makefile, the value of TBL
 is empty.

 **Diagnosis**:
 There is no `tbl` in $PATH, so the configuration phase (for libbind)
 doesn't find it and leaves it blank.

 **Fix**:
 `port install groff` (since groff contains `tbl`) followed by `port clean
 libbind` and `port install libbind`.

 **Proper fix**:
 make `groff` a dependency of `libbind` so it's automatically installed.
