 These new lines in changeset 53301 to the libXaw Portfile

 {{{
 # Delete this, so it searches its own headers first rather than installed
 ones
 configure.cppflags-delete -I/opt/local/include
 }}}

 break the build if it causes configure.cppflags to be deleted completely.
 I get an error

 can't read "configure.cppflags"

 If I add the following line after the delete, it builds ok, but I don't
 know enough to say if that is the correct fix:

 {{{
 configure.cppflags-append -I/opt/local/include
 }}}
