Hi All

I'm using ports-mgmt/pkg to installing got "file not found" failed even if it was previously installed

# pkg --rootdir [JAIL] which /usr/local/share/sysconftool/sysconftool and result.

/usr/local/share/sysconftool/sysconftool was installed by package sysconftool-0.22

/usr/local/share/apache24/misc/index.html existence in installation target jail.

Can all help me debug?
Thanks all.
