Hello there. Unfortunately I can't find the Alien::igraph, did you post that somewhere? No matter though.

From a cursory look at the igraph library, it seems igraph API expects you to manage the allocation of igraph_t structure on your own. Either a static or malloc'ed struct, but you have to allocate it somewhere. From this I presume you'd want a chunk (sizeof(igraph_t)) of opaque data in your perl object, not an opaque pointer. HtH.
