SystemTap's configure.ac contains Bashisms (use of == operator with test built-in). Thus, configure throws some errors when /bin/sh is not Bash. This doesn't cause the build to fail outright, but it may be causing misdetection of features. Suggest setting CONFIG_SHELL=/bin/bash when running configure. Example configure output follows.

Created attachment 640244 [details, diff] fix-configure-bashisms.patch Alternatively, the attached patch can be applied to remove the Bashisms and allow dev-util/systemtap-4.0-r1 to configure without errors using Dash as /bin/sh.
Also fails to install the dtrace binary
