regex error: runaway multi-line !! string starting on line...

I appreciate the suggestions from Mike, Michael and John around my log
parsing questions.

When attempting to match 'or' conditions using the the m!! and x pattern
match operators, would this construct be correct?

In other words, does this m// attempt :

# match lines begining with #, or lines that contain 'CommmunityID=399', or
lines that contain these paths

 if (
m/^#|CommunityID\=399|\/developersupport\/testfiles|\/remotegadgets\/marks\/
gadget/ ) {
          print NEWLOG;

equate to this m!!x attempt:

    21                  while ( my $line =  <LOG> ) {
    22                          while ( m!
    23                                  ^#   # match lines that start with
'#'
    24                                  CommunityID=399      # or lines that
contain
    25                                  /developersupport/testfiles
    26                                  /remotegadgets/marks/gadget/
    27                          !x)  
    28                  print NEWLOG;
    29                  }    

When running with strict and use diagnostics, I get this error.
