Summary:                    [patch] Can't build asterisk using just
--with-netsnmp... seems to always want to use CONFIG_NETSNMP
Description: 
It's issue 15714 all over again, only with netsnmp instead of curl this
time.

If you've built a different version of netsnmp (or patched it) and you
want to build against that, you can't.

Configure will attempt to find net-snmp-config and run that...  which
might not be in any place it will likely be discovered... and ignores where
you've told 'configure' to actually find the headers and libraries.

---------------------------------------------------------------------- 
I've been researching this, and I'm not entirely sure that it is a bug--or
at least one that is easily fixable. We use the net-snmp-config utility (as
we should) and it returns all kinds of things for the agent-libs.  On my
machine:

terry at cesium:~/src/digium/asterisk/trunk$ net-snmp-config
--agent-libs-Wl,-Bsymbolic-functions -L/usr/lib -lnetsnmpagent
-lnetsnmphelpers -lnetsnmpmibs -lnetsnmp -Wl,-E

The purpose of using this utility is so complex things like this do not
have to be hard-coded anywhere. The only way I could see to make this work
with a passed in directory would be to do some kind of search and replace
on the net-snmp-config output--which seems quite brittle.

I think the real solution to this issue is to run configure with your
PATH=/path/to/new/net-snmp-config:$PATH so that the proper net-snmp-config
is found and the proper options can be set.

With that said, I'm attaching a patch that makes the AST_EXT_TOOL_CHECK
take the directory passed via --with-*=${dir} and search for the *-config
app in ${dir}/bin. This *should* find the correct installation of the
library.

Please apply the batch, run ./bootstrap && ./configure
--with-netsnmp=/your/path/to/netsnmp and test it out for me.
