Config Fail on x86_64 systems

[gnalsa]

While trying to setup PCS, error finding libpcap is returned.

python setup.py config

raise "couldn't find pcap build or installation directory"

libpcap drivers are installed:

find / -iname "libpcap"

/usr/lib/x86_64-linux-gnu/libpcap.so.0.8
/usr/lib/x86_64-linux-gnu/libpcap.so
/usr/lib/x86_64-linux-gnu/libpcap.a
/usr/lib/x86_64-linux-gnu/libpcap.so.1.5.3

Was able to fix by modifying the directories searched
for sd in ('lib', 'lib/x86_64-linux-gnu'):
for lib in (('pcap', 'libpcap.a'),
('pcap', 'libpcap.dylib'),
('wpcap', 'wpcap.lib')):

python setup.py config

running config
found {'libraries': ['pcap'], 'library_dirs': ['/usr/lib/x86_64-linux-gnu'], 'include_dirs': ['/usr/include/pcap']}
