Description:
------------
This may very well be a debian specific bug, I couldn't honestly say.

However, when I run:
phpize
./configure
make
make install
on the snmp library to run as a dynamic module then it compiles fine - but config.h defines the values for HAVE_SNMP_PARSE_OID as undefined when infact the relevant header files are installed. This means that doing an snmpwalk("host","community",$OID) will just keep running and eventually timeout. This seems to happen no matter what $OID is, aside from "system" - it works fine like that.

Reproduce code:
---------------
// note, this was testing again a 3com superstack3 switch

$a = snmpwalk($host, $community, "ifDescr");

print_r($a);

Expected result:
----------------
