BitcoinUnlimited: Compiling gives error "make[2]: *** [libbitcoin_server_a-main.o] Error 4"

I’m trying to switch my node over to BU, but I’m running into errors on compilation. Any help is appreciated! I’m compiling this on bitnodes hardware running:

bitnodes@bitnodes-hardware:~/src/bu-src$ cat /etc/lsb-release
DISTRIB_ID=Ubuntu DISTRIB_RELEASE=14.04 DISTRIB_CODENAME=trusty DISTRIB_DESCRIPTION=“Ubuntu 14.04.5 LTS”

I ran these commands for the install:

$ mkdir -p ~/src $ cd ~/src $ git clone https://github.com/BitcoinUnlimited/BitcoinUnlimited.git bu-src $ cd bu-src $ git checkout bu0.12.1c $ ./autogen.sh $ ./configure --without-gui --without-miniupnpc --disable-wallet $ export NUMCPUS=grep -c '^processor' /proc/cpuinfo $ make -j$NUMCPUS

Here is the output from the last command (make) with errors:
