Summary:                    mquery() related bug
Description: 
The problem reveil it self in two ways. One is that you sometime notice in
the output during a lin that grep couldn't find /tmp/xxxxx file but then
continues as nothing happend.

The second problem is a lot more alarming though. If you do lin -cr on a
module that use MQUERY those OPTS will not be passed on properly to $OPTS
during that lin. It will however write the correct options to
/etc/lunar/local/depends/$MODULE. So the next time you do lin -c (without
-r) $MODULE it will actually pick up your MQUERY settings properly. 

Apache2 is a great module to test this with, simply run lin -cr apache2
and make some random choices. Then abort the lin after the ./configure
step and examine config.log and you will notice that the options are
missing. Then run lin -c apache2 again and do the above steps again and
the options are there.

I have located where the problem occur in /sbin/lin in this section of the
code:

  # different approaches for multiple modules (start up downloads first)
  # and single modules (plain install)
  if [ -z "$SINGLE_MODULE" ] ; then

    if [ -z "$TEMP_DOWNLOAD_PIDS" ] ; then
      export TEMP_DOWNLOAD_PIDS=$(temp_create "download-pids")
      export TEMP_PREPAREDDEPS=$(temp_create "prepared-depends")
      export TEMP_CONFIGOPTS=$(temp_create "configopts")
    fi

----- snip -----
    
If you move the line  "export TEMP_CONFIGOPTS=$(temp_create "configopts")"
outside that if-statement everything work just fine. But since I'm not
entirely sure where the correct place for that line would be I will leave
it for you to fix (sofar) ;)

This diff solves the issue. 
When you see 
grep: /tmp/lunar.lin.19392..JosQX19420: No such file or directory
during a lin this is related to this bug. And it only happen in rare
conditions where a optional dependency isn't installed and when mquery()
is used if I remember correctly.
