That failure has nothing to do with libscream.c, the error that stopped the build was this one:

/usr/bin/ld: ./.libs/libEterm.so: undefined reference to `MEMSET'
collect2: error: ld returned 1 exit status

The use of MEMSET() was removed in commit 5d475d0. It sounds like you might have been trying to build the 0.9.6 release sources, which are from 2011. (Ignore the tag date being 2020, that's just from the sourceforge migration. The latest commit in 0.9.6 is from 2011.) You definitely should use the master branch, instead of 0.9.6.
