#20002: bugs in vtk-devel Portfile on Tiger

Comment(by dweber@…):
I think the line in question is in the doc variant, where we have:
{{{
system "ln -Fhs ${vtkDocPath} ${destroot}/${vtkDocPathLink}"
}}}
So this is a system ln command (not a tcl ln command, as in some other
variants).
On my leopard system, `man ln` contains the following:
{{{
1 LN(1) BSD General Commands Manual LN(1)
...
20 -F If the target file already exists and is a directory, then
remove it so that the link may occur.
21 The -F option should be used with either -f or -i options. If
none is specified, -f is implied.
22 The -F option is a no-op unless -s option is specified.
...
24 -h If the target_file or target_dir is a symbolic link, do not
follow it. This is most useful with
25 the -f option, to replace a symlink which may point to a
directory.
...
37 -s Create a symbolic link.
}}}
As I read this, it will create a symbolic link for a directory, replacing
the symlink if it exists already.
Are we reading different man pages?
Suggestion. Take a look at the other variants where a tcl ln command is
used. I don't recall exactly why this doc variant uses a system ln
command, but I do recall that the symlinks created in ${prefix}/share/doc
are not exactly what I want.
What I really want is this:
{{{
/opt/local/share/doc/vtk-5.4 -> /opt/local/share/vtk-5.4/doc
}}}
This is what I get:
{{{
/opt/local/share/doc/vtk-5.4/doc -> /opt/local/share/vtk-5.4/doc/
}}}
This is how it is defined, in a nutshell (after consolidating a few things
from the Portfile):
{{{
set vtkDocPath ${prefix}/share/${distname}/doc
set vtkDocPathLink ${prefix}/share/doc/${distname}
system "ln -Fhs ${vtkDocPath} ${destroot}/${vtkDocPathLink}"
}}}
I have no idea why the vtkDocPathLink actually becomes
${prefix}/share/doc/${distname}/doc
Best,
Darren
