/opt/desmond2012/maestro-v93023/lib/Linux-x86_64/libstdc++.so.6: version `GLIBCXX_3.4.11' not found (required by /usr/lib/pymodules/python2.7/matplotlib/ft2font.so)
The solution is to instal the GNU C compiler and GNU C++ compiler for x86_64.
To install the gcc and g++ compilers, you will need the build-essential package. This will also install GNU make.
build-essential contains a list of packages which are essential for building Ubuntu packages including gcc compiler, make and other required tools.
$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get install build-essential
$ gcc -v
$ make -v
Then,
$ cd /opt/desmond2012/maestro-v93023/lib/Linux-x86_64
$ sudo mv libgcc_s.so.1 libgcc_s.so.1.back
$ sudo ln -s /lib/libgcc_s.so.1 libgcc_s.so.1
$ sudo rm libstdc++.so.6 (this was already a symbolic link)
and finally create a symbolic link
$ sudo ln -s /usr/lib/gcc/x86_64-linux-gnu/4.6.1/libstdc++.so libstdc++.so.6
Hope that helps!
