make error while installing on Solaris 10

[Jawahar Balakrishnan (JB)]

I tried version 4.3.2 and 4.0.11 but i get the same error when i
execute make. Any ideas/thoughts will be appreciated.

InetIfReq.cc: In constructor âInet6IfAliasReq::Inet6IfAliasReq(const
String&, const InAddress&, const InAddress&)â:
InetIfReq.cc:38: error: âSIOCGIFINDEXâ was not declared in this scope
InetIfReq.cc:40: error: âstruct ifreqâ has no member named âifr_ifindexâ
make[3]: *** [InetIfReq.o] Error 1

Thanks
