biocParallel error when installing

[billytcl]

R 3.2.5

Installing from devtools gives me this error:

Installing BiocParallel '/usr/lib/R/bin/R' --no-site-file --no-environ --no-save --no-restore --quiet CMD
INSTALL '/tmp/RtmpBv2SbE/devtools881174ee69a1/BiocParallel'
--library='/home/billylau/R/x86_64-pc-linux-gnu-library/3.2' --install-tests

• installing source package ‘BiocParallel’ ... ** R ** inst ** tests ** preparing package for lazy loading ** help *** installing help indices ** building package indices ** testing if installed package can be loaded Error : .onLoad failed in loadNamespace() for 'BiocParallel', details: call: makePSOCKcluster(spec, ...) error: numeric 'names' must be >= 1 Error: loading failed Execution halted ERROR: loading failed

The same thing happens when directly instaling with biocLite.

Has anyone seen this problem before?
