Hi Martin,
Following your suggestion, I added these 2 files.
1.
*repos/libports/src/lib/jitterentropy/spec/riscv/jitterentropy-base-genode-nstime.h*
Its contents are:

2. *repos/libports/lib/mk/spec/riscv/jitterentropy.mk

And I updated the jitterentropy jitterentropy import file at
*repos/libports/lib/import/import-jitterentropy.mk
<http://import-jitterentropy.mk>*
Its contents are:

I am getting such error:

I am not able to fix this. Please help me understand the issues.
