>Description:
xrx-1.0.3 fails to build with libxul-1.9.2.17 installed. The output of configure changes in the presence of /usr/local/include/libxul/npapi.h from no to yes:

checking npfunctions.h usability... yes
checking npfunctions.h presence... yes
checking for npfunctions.h... yes

moving the file aside makes the build succeed. While the header is present, The warnings appear during compile earlier in the build in addition to right with the error:

>How-To-Repeat:
install www/libxul then try to build x11/xrx
>Fix:
move /usr/local/include/libxul/npapi.h, configure port, move file back, build and install. I do not know how to tell configure to not see it, nor do I know how to make it just work with the file being present but either would be a fix for the ports tree. sed could edit the output of configure or configure itself to appear to not locate the file.
