The system does NOT think any of these ports are installed. I ran "pkg info" on all of them and none showed up as installed. None was installed when I re-installed linux-c7-gtk2. That includes atk, pango, gdkpixbf2 or png (the linux-c7 versions). linux-c7-gtk2 sis install with only the message about the lack of libpng-15.so.15 that I mentioned. I suspect that these ports have been missing since I moved to 11.0-BETA, deleted all ports and reinstalled. At that time nspluginwraper installed without failing, but it looks like the USES_LINUX dependencies were not re-installed, so any problem probably goes back that far, though it is possible that they were deleted more recently. To be clear, I have been using BSD for over 40 years, originally when doing some work for UC Davis and FreeBSD for over 20 years. I am quite conversant (though not expert) in make and Makefiles. I have been using ports for over 20 years and pkg since back when bapt@ was still doing beta testing. my concern is that these ports were clearly NOT installed and that I could install nspluginwrapper and, later, linux-c7-gtk2 without the ports system noticing the missing dependencies. -- Kevin Oberman, Part time kid herder and retired Network Engineer E-mail: rkoberman@gmail.com PGP Fingerprint: D03FB98AFA78E3B78C1694B318AB39EF1B055683
