 At the end of upgrading the outdated ports:

 {{{
 --->  Updating database of binaries
 DEBUG: Updating binary flag for file 1 of 1:
 /opt/local/share/man/man1/dot2gxl.1
 --->  Scanning binaries for linking errors
 }}}

 But:

 {{{
 pete 124 /\  l /opt/local/share/man/man1/dot2gxl.1
 lrwxr-xr-x  1 root  wheel  8 18 Dez 11:38
 /opt/local/share/man/man1/dot2gxl.1 -> gv2gxl.1
 pete 125 /\ l -L /opt/local/share/man/man1/dot2gxl.1
 lrwxr-xr-x  1 root  wheel  8 18 Dez 11:38
 /opt/local/share/man/man1/dot2gxl.1 -> gv2gxl.1
 ls: dot2gxl.1: No such file or directory
 Exit 1
 }}}

 And but again:

 {{{
 lrwxr-xr-x  1 root  wheel   8 18 Dez 11:38
 /opt/local/share/man/man1/dot2gxl.1 -> gv2gxl.1
 lrwxr-xr-x  1 root  wheel  11 11 Jan  2019
 /opt/local/share/man/man1/dot2gxl.1.gz -> gxl2gv.1.gz
 pete 128 /\ l -L /opt/local/share/man/man1/dot2gxl.1*
 lrwxr-xr-x  1 root  wheel     8 18 Dez 11:38
 /opt/local/share/man/man1/dot2gxl.1 -> gv2gxl.1
 -r--r--r--  1 root  wheel  1082 18 Dez 11:38
 /opt/local/share/man/man1/dot2gxl.1.gz
 ls: dot2gxl.1: No such file or directory
 Exit 1
 }}}

 Is Makefile incorrectly set up?

 {{{

 …/graphviz-devel/work/graphviz-2.50.0/cmd/tools/Makefile:1551:  (cd

 (cd $(DESTDIR)$(man1dir); rm -f dot2gxl.1; $(LN_S) gv2gxl.1 dot2gxl.1;)
 }}}

 The mentioned Makefiles do not reference dot2gxl.1.gz. Compressing all
 manual files seems to be a speciality of `port`…
