Can't compile vnsi server plugin

Hey,

I'm trying to compile the VDR server plugin - since moving to Ubuntu 13.04 my VDR version is now 2.0.1 so I just type make but I get the following error - which looks related to missing src - not really sure what to do at this point...

grep: /config.h: No such file or directory
grep: /config.h: No such file or directory
g++ -c -D_GNU_SOURCE -DPLUGIN_NAME_I18N='"vnsiserver4"' -DVNSI_SERVER_VERSION='"0.9.2"' -I/include -o vnsi.o vnsi.c
vnsi.c:27:24: fatal error: vdr/plugin.h: No such file or directory
compilation terminated.
make: *** [vnsi.o] Error 1
