[GRASSLIST:4875] v.in.dgn problem

[gis Lab]

            Hi everybody, 
  I have grass5.0 on my machine and during the compilation I did not get any errors. Despite of this the v.in.dgn (v.out.dgn also) module was not compiled. Now I needed to use it and I run gmake5 -i to build it but it exit with error. The error message says that the file dgnlibp.h does not exist. It search for it in ../include. 
  If someone knows how to fix this or can tell me from where I can get the header file please write me.
