IPS pkgrecv on RedHat

Is there a way to retrieve solaris IPS packages from the Oracle repositories from a RedHat machine? I found https://java.net/projects/ips (which seems maintained) and tried to compile it on RedHat, eventually ending up at some errors like: _pspawn.c:497:21: error: ‘posix_spawn_file_actions_t’ has no member named ‘__file_attrp’ { void * *tmp = &p->__file_attrp; (void)tmp; } ^ _pspawn.c: In function ‘_cffi_checkfld_typedef_posix_spawnattr_t’: _pspawn.c:506:21: error: ‘posix_spawnattr_t’ has no member named ‘__spawn_attrp’ { void * *tmp = &p->__spawn_attrp; (void)tmp; } The files from that project are a bit misleading (we even have .bat files there ...). Can that actually be compiled on a non-Solaris machine or is there an alternative?
