That's because NetBSD and FreeBSD for instance don't include /usr/local in their system compilers' default paths. Not OpenVPN's fault. Sure you can script around that but it's never complete (there's always one more system with one more installation location that we won't cover) and gets ugly quite quickly. Look at how fetchmail tries to hunt down the various Kerberos, GSSAPI, SSL libraries, their individual dependencies and inter-dependencies and everything. It's a mess. pkg-config could help here, but ISTR that LZO doesn't install a .pc file. Possibly check the autoconf macro archives if they have a lzo helper .m4 file, point me to it and I may have another look. >> Unless you install from Blastware, or Sunfreeware, or Pkgsrc, or OpenPKG, >> or... >> (you name it) -- each with its own default directories. > > Yeah, sure.

The 95% case on a given distribution is that the distributor packages OpenVPN and the user doesn't care beyond that point. > "If other packages can get this automatically, why do we need switches > for OpenVPN"? Document that and be done. It helps the user much more than convenience hacks. -- Matthias Andree
