Snort configure problem with snmp???

["Ronald Tse" <ronald () vitagreen com>]

Dear Everyone,

I have used snort for a year and had no problems or whatever...
But as I am trying to upgrade to Snort 1.8.7 or 1.9.0b2 I receive the following errors from configure with 
"--with-snmp":

**********************************************
  ERROR: unable to find snmp headers (snmp_parse_args.h in ucd-snmp-4.2.1)
  checked in the following places
        /usr/include
        /usr/include/ucd-snmp
        /usr/local/include
        /usr/local/include/ucd-snmp
**********************************************

I am using ucd-snmp 4.2.5 and the file is in /usr/local/include/ucd-snmp...
I also have used --with-openssl after looking in the archives, but the same error still comes out.
The box is RH 7.3.

Can anyone help?

Thanks
Ronald Tse
