[OctDev] Problem compiling octave-forge

[Ralph <oct...@sp...>]

Something is missing, but I don't know the library. Could someone help me?
 
 The first error msg is:
 ======================
 rand.cc: In function `void do_size(octave_value_list, int&, int&)':
 rand.cc:139: error: `xisnan' undeclared (first use this function)
 rand.cc:139: error: (Each undeclared identifier is reported only once for 
each 
 function it appears in.)
 make[1]: *** [rand.oct] Error 1
 =======================
 
 and the 2nd:
 
 =======================
 coupling_3j.cc: In function `octave_value_list Fcoupling_3j(const 
 octave_value_list&, int)':
 coupling_3j.cc:74: error: `NDArray' undeclared (first use this function)
 =======================
