I would guess that your machine (SCO) does not have rint(). IGRAPH
probably stands for Intergraph. Try the following:

/* #ifdef IGRAPH */
#define rint(x) ((double) ((int) ((x) + 0.5)))
/* #endif */

A more permanent fix may be to put
#define G_rint(x) ((double) ((int) ((x) + 0.5)))
in one of the GRASS include files and replace all occurrences
of rint() with G_rint().
