Hello,
while preparing my patches for OS X I also noticed that the build is
broken on OS X:
[...]
checking net/if_tun.h usability... no
checking net/if_tun.h presence... no
checking for net/if_tun.h... no

configure: error: no tap header could be found
The bad commit is: 7cacdfd4b7f221139e0d2a0334f1f1cd8f2a1b75
build: tap: search for tap header
It aborts build if no tap headers is found. If the check is disabled
configure works but the build still does not work.
In the INSTALL file --with-lzo-headers and --with-lzo-lib is mentioned,
which do not work:
checking for aes_crypt_cbc in -lpolarssl... no
checking for lzo1x_1_15_compress in -llzo2... no
checking for lzo1x_1_15_compress in -llzo... no
checking for PKCS11_HELPER... no
configure: error: lzo enabled but missing
./configure --help mentions LZO_CFLAGS and LZO_LIBS which work a bit
better but still do not work.
LZO_CFLAGS="-I/opt/local/include" LZO_LIBS=-L/opt/local/lib ./configure

I have no idea about the configure, autotools internal to fix this.
