It will have "Formatting page, please wait..." at the start. The man2html
port has just been fixed. What was happening was that STDERR was being
closed before man.cgi called man(1). If the catpage didn't exist you get
the "Formatting....." message but, since STDERR is closed, it goes to
STDOUT and so ends up at the start of the catpage, before the output from
gzip. Then when man(1) tries to view the page gzip(1) can't understand the
file.
If you can't update the port just move the line ``close(STDERR)'' in
man.cgi thus:
# Convert output from man to html
#--------------------------------
From here>>># close(STDERR);
open(MANPRG, "-|") or exec($ManPrg, @manargs);
$Man2Html::InFH = \*MANPRG; # set input filehandle
require $ManConvPrg or
error("Problem executing man->HTML converter");
To here>>> close(STDERR);
The problem with missing lines can be cured by setting ``-topm'' and
``-botm'' to 0, either in man.cgi itself (the ``@ConvArgs'' line) or as an
option when man.cgi is run. I haven't figured out exactly why this occurs,
but it seems to be due to FreeBSD manpages being in 2 formats; -mdoc and
-man.
