I guess the question I was really asking is "is this another mess 
similar to the one induced by Red Hat's brilliant idea of installing 
libpcap's pcap.h in /usr/include/pcap, rather than in /usr/include where 
it's installed on most other OSes, or is the standard location for it 
/usr/include/pcre, so that the Ethereal configure script is wrong and 
has always been wrong?"

I.e., where is pcre.h installed by the standard PCRE distribution from 
www.pcre.org and, if it's in "/usr/include" and/or "/usr/local/include", 
did the creators of your system decide it should've been installed in 
its own subdirectory - which, arguably, it should have been, just as 
pcap.h arguably should have been, but trying to improve this *after the 
fact* just requires configure scripts to go through more crap to cope 
with the "improved" location as well as the standard one?
