make PythonAPI throwing error for boost

[SarathHari90]

I am getting below error from boost library while doing the "make PythonAPI" command.

Setup.sh: Extracting boost for Python 3.
Building Boost.Build engine with toolset clang...
Failed to build Boost.Build build engine
Consult 'bootstrap.log' for more details
Util/BuildTools/Linux.mk:137: recipe for target 'setup' failed
make: *** [setup] Error 1

This is in Ubuntu 18.04 linux build. Can someone shed some light here?
