The script devel-envs.sh is a Bourne shell script, so I guess "sourcing" it like c shell
scripts isn't appropriate here, it fails, executed from POCL's BUILD directory:

source ./tools/scripts/devel-envs.sh
libs_subdir=.: Command not found.
export: Command not found.
export: Command not found.
export: Command not found.
export: Command not found.

[...]

Executing

# (sh ./tools/scripts/devel-envs.sh && clinfo)

gives me 

Unable to find symbol pthread_mutexattr_setkind_np version (null). Aborting.
Abort

This is something I see lately very often due to some weirdness in registering ICDs. This
is with compiling pocl with LLVM 6.

Installed (on my test box) is ocl-icd 2.2.12, on another box there is the regular ocl-icd
package/port devel/ocl-icd in the FreeBSD ports tree, which is version 2.2.11. this just
for the record if it matters.
