[click] bug in INSTALL file / finding directories

[Douglas S. J. De Couto]

as far as i can tell, the variables PCAP_HEADER_PATH and 
PCAP_LIBRARY_PATH mentioned in the INSTALL file have no basis in reality.

i.e. they only seem to exist in that INSTALL file.

probably the user needs to specify the CFLAGS or LDFLAGS environment 
variables before running configure if they need to look somewhere 
strange for libpcap.

e.g.
setenv LDFLAGS=-L/my/lib/dir
setenv CPPFLAGS=-I/my/include/dir

The CPPFLAGS variable must be set for configure to find the headers.  I 
guess you could set the CFLAGS or CXXFLAGS to specify different include 
dirs for C vs. C++, but I don't know if configure will pick up headers 
in directories specified that way.

i have spent all day trying to remember how to cross-compile click for 
the ipaq... the lesson is, once you figure it out, write a script to do 
it for you!

cheers
