The linker problem isn't isolated to clang, here it is with gcc-4.9:
{code}
/usr/bin/g++-4.9 -ggdb -O0 -Wall -Wconversion -Wno-sign-conversion
-Wno-unknown-warning-option -Werror -std=c++11 -msse3 -Werror

I guess because no Boost symbols are used that the binary produced by gcc does
not have the runtime dependency on the .so files:
{code}
$ ldd debug/plasma_store
linux-vdso.so.1 => (0x00007ffd8390b000)
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0
(0x00007f9ab8354000)
libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6
(0x00007f9ab8041000)
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f9ab7d3b000)
libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1
(0x00007f9ab7b24000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f9ab775b000)
/lib64/ld-linux-x86-64.so.2 (0x00007f9ab8572000)
{code}
But the Boost libraries shouldn't be passed to the linker at all

> I'm not sure why, but when I run the pyarrow test suite (for example
