[vdr] epgsearch compile error vdr-1.5.2

I'm getting the following error when I try and compile epgsearch-0.9.19

Plugin epgsearch: make[1]: Entering directory `/usr/src/development/vdr-1.5.2/PLUGINS/src/epgsearch-0.9.19' g++ -g -O2 -Wall -Woverloaded-virtual -fPIC -c -D_GNU_SOURCE -DPLUGIN_NAME_I 18N='"epgsearch"' -I../../../../DVB/include -I../../../include -I../../../.. /DVB/include conflictcheck.c conflictcheck.h: In member function 'int cConflictCheckDevice::ProvidesCa(const cChannel*) const': conflictcheck.h:106: error: 'class cDevice' has no member named 'ProvidesCa' make[1]: *** [conflictcheck.o] Error 1 make[1]: Leaving directory `/usr/src/development/vdr-1.5.2/PLUGINS/src/epgsearch-0.9.19'

Any ideas?
