Hi Michael!
Thank you for libcoin! It is a awesome evolution for Bitcoin and for the
CryptoCurrencies as a hole... Thanks!!!
Anyway, I am unable to compile libcoin under my Ubuntu 11.04. At this
machine, I have compiled and running Bitcoin (from sources), Namecoin,
Devcoin, Litecoin, IXcoin and I0coin, all from sources but, when I try to
compile libcoin, I got:

The build system is configured to install libraries to /usr/local/lib
Your applications may not be able to find your installed libraries unless
you:
set your LD_LIBRARY_PATH (user specific) or
update your ld.so configuration (system wide)
You have an ld.so.conf.d directory on your system, so if you wish to ensure
that
applications find the installed libcoin libraries, system wide, you could
install an
libcoin specific ld.so configuration with:
sudo make install_ld_conf

Now I tried make, without success:
