Compile develop branch error

[ebookx]

when I try to compile develop branch.

/usr/bin/ld: b58/b58.o (symbol from plugin): in function b58_csum': (.text+0x0): multiple definition of ripemd160_xform_func'; brainflayer.o (symbol from plugin):(.text+0x0): first defined here

lto-wrapper: warning: using serial compilation of 2 LTRANS jobs
collect2: error: ld returned 1 exit status
make: *** [Makefile:109: brainflayer] Error 1
