 Dear mlpack developers,
 I have downloaded and configured (cmake) mlpack on Ubuntu 14.04. However
 when I try to build it I encounter the following error:

 Linking CXX executable ../../../../bin/sparse_coding
 /usr/bin/ld: warning: libgfortran.so.3, needed by //usr/lib/libblas.so.3,
 not found (try using -rpath or -rpath-link)

 collect2: error: ld returned 1 exit status
 make[2]: *** [bin/sparse_coding] Error 1

 make: *** [all] Error 2

 When I try to see the linked libraries with ldd /usr/lib/libblas.so.3, I
 get:

         linux-vdso.so.1 =>  (0x00007fffa6c95000)
         libgfortran.so.3 => not found
         libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1
 (0x00007f4dc1ab5000)
         libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0
 (0x00007f4dc1896000)
         libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f4dc1590000)
         libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f4dc11ca000)
         /lib64/ld-linux-x86-64.so.2 (0x00007f4dc22b8000)

 However libgfortran.so.3 is in /usr/lib/i386-linux-gnu/.
 I also defined the variable LD_LIBRARY_PATH to include the above dir but
 it did not work.
 Still no luck when trying ldconfig -n /usr/lib/i386-linux-gnu/ or creating
 the file mlpack.conf (with the line /usr/lib/i386-linux-gnu/) in
 /etc/ld.so.conf.d/

 I don't know how to proceed further to get mlpack installed. I hope you
 can help me finding a solution to this problem.

 Thank you,
 Fabio
