Unable to install Rsamtools

[kubu4]

There seem to be two potential issues (see log below):

1. /bin/bash: -c: line 0: syntax error near unexpected token ('`

2. /opt/microsoft/ropen/4.0.2/lib64/R/etc/Makeconf:159: recipe for target 'Biostrings_stubs.o' failed

Would anyone have any suggestions on what's happening and how to tackle this?
