Fatal error: 'sys/_pthread/_pthread_condattr_t.h'

[datasci-iopsy]

I'm currently attempting to update data.table and I see that the binary version available (1.12.8) but the source version is later (1.13). I've tried to use the instructions via the Wiki but to no avail. I continue to get the following errors:

In file included from fwrite.c:10:

#include <sys/_pthread/_pthread_condattr_t.h>
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

make: *** [fwrite.o] Error 1
ERROR: compilation failed for package ‘data.table’

I've installed using homebrew and even navigated the ASCII files in an attempt to include the missing file but nothing seems to work. Should I just wait for CRAN to catch up or is this a fixable issue?

Thanks in advance!
