This is manifesting with a freshly built buildroot and the stock fw:

opendingux:/media/data/local/home # ls -l /usr/lib/libshake.so.1
-rwxr-xr-x    1 root     root         12564 Oct 27 04:27 /usr/lib/libshake.so.1
opendingux:/media/data/local/home # ls -l /usr/lib/libshake.so
lrwxrwxrwx    1 root     root            65 Oct 26 19:58 /usr/lib/libshake.so -> /home/tonyjih/RG350_buildroot/output/target/usr/lib/libshake.so.1

Copying the library to /usr/local/bin won't help.

Is this a known problem?

Are you trying to build it for windows or for MIPS ?
libshake isn't provided by default on the toolchain, you have to compile it yourself. /usr/local/bin is your host compiler, DO NOT USE MIPS LIBRARIES for X86 !
