Comment (by todofixthis):

 I'm trying to get this to work, but I'm running into an error that I'm not
 sure how to resolve.

 I made the following changes:

 * Added `mongodb.conf.sample` to `${portpath}/files`.
 * Added the following to `Portfile`:

 {{{
 post-activate {
     if {![file exists ${prefix}/etc/mongodb/mongodb.conf]} {
         file copy ${filespath}/mongodb.conf.sample \
             ${prefix}/etc/mongodb/mongodb.conf
     }
 }
 }}}

 * `cd ${portpath}`
 * `sudo port install`

 This is the error that I get (note:  `/private/tmp/mongodb` is the
 directory containing the Portfile):

 {{{
 :debug:activate Executing proc-post-org.macports.activate-activate-0
 :error:activate org.macports.activate for port mongodb returned: error
 copying "/private/tmp/mongodb/files/mongodb.conf.sample" to
 "/opt/local/etc/mongodb/mongodb.conf": no such file or directory
 :debug:activate Error code: NONE
 :debug:activate Backtrace: error copying
 "/private/tmp/mongodb/files/mongodb.conf.sample" to
 "/opt/local/etc/mongodb/mongodb.conf": no such file or directory
     while executing
 "proc-post-org.macports.activate-activate-0 org.macports.activate"
     ("eval" body line 1)
     invoked from within
 "eval $post $targetname"
 :info:activate Warning: targets not executed for mongodb:
 org.macports.activate
 }}}

 I confirmed that `/private/tmp/mongodb/files/mongodb.conf.sample` does
 exist.

 I think the error is indicating that it can't copy the file to
 `/opt/local/etc/mongodb` because that directory doesn't exist, but even if
 I add `xinstall -d ${prefix}/etc/mongodb` to the Portfile, I still get the
 same error.

 I'm not sure how to continue; any ideas?
