The issue is that there are many open source licenses and they aren't
always compatible.  Even with GPL, there is GPLv2-only,
GPLv2-or-later, and GPLv3-only, which can't always be mixed freely.
Oh, and don't forget the LGPL licenses.  And then there is Nmap, which
is GPLv2 with some extra terms such as allowing linking to OpenSSL.
Here is a list of well over 50 open source certified licenses:

So yeah, integrating code from other projects definitely requires
care.  The good news is that many of the licenses are compatible, and
that is how we are able to use libdnet, libpcre, libpcap, winpcap,
lua, OpenSSL, etc.
