Note: uses the  s///r substitution regex modifier available with Perl version 5.14+. This is easily worked around if not available. 

>perl -wMstrict -MData::Dump -le
"my $line =
   'Lorem ipsum dolor sit amet, consectetur adipisicing elit.'
 ;;
 my @array = ('ipsum', 'sit amet', ' elit ');
 my ($avoid) =
   map qr{ $_ }xms,
   join ' | ',
   map s{ \s+ }' \s+ 'xmsgr,
   map s{ \A \s+ | \s+ \z }''xmsgr,
   @array
   ;
 print $avoid;
 ;;
 my @got = $line =~ m{ (?: $avoid (*SKIP)(*FAIL))?  [[:alpha:]]+ }xmsg
+;
 dd \@got;
"
(?^msx: ipsum | sit \s+ amet | elit )
["Lorem", "dolor", "consectetur", "adipisicing"]
