How did you install it? Because you can't install that using the Dolphin interface: it will inform you about an error ("noticed HTML page") and then redirects you
here.
So what did you do with the tarball? If you didn't mess with a tarball then you haven't actually installed the plugin, and that would explain why it doesn't work.
(edit)
Your best bet to get access to more Dolphin services is
devel/dolphin-plugins-kde4, but that's most likely already installed because
devel/kdesdk-kde4 depends on it which in its turn is required by the main KDE4 meta package.
I just checked the tarball I mentioned above and as also mentioned by
k.jacker below my post your main problem is that most KDE software has Linux in mind, and Linux and FreeBSD differ in many ways, one of which being the location of the installed software.
Regular KDE software / add-ons would assume things to be installed in
/usr whereas FreeBSD uses
/usr/local. You can see this quite clearly within the
Makefile within the archive:
Code:
PREFIXmenu5=$(RPM_BUILD_ROOT)/usr/share/kservices5/ServiceMenus
PREFIXservicetypes5=$(RPM_BUILD_ROOT)/usr/share/kservicetypes5
PREFIXmenu=$(RPM_BUILD_ROOT)/usr/share/kde4/services/ServiceMenus
PREFIXapp=$(RPM_BUILD_ROOT)/usr/share/applications
PREFIXSVGicons=$(RPM_BUILD_ROOT)/usr/share/icons/hicolor/scalable/apps
PREFIXmime=$(RPM_BUILD_ROOT)/usr/share/mime/text
PREFIXappmerge=$(RPM_BUILD_ROOT)/etc/xdg/menus/applications-merged
PREFIXdeskdir=$(RPM_BUILD_ROOT)/usr/share/desktop-directories
PREFIXdoc=$(RPM_BUILD_ROOT)/usr/share/doc/kde-services
This is never going to work on FreeBSD without proper modifications. Well, maybe apart from the
/usr/share/doc link but even that would basically "ruin" things because that location is reserved for the base system only. The right location would be
/usr/local/share/doc.
Alas, this might not be the right tool for the job
