I'm trying to build R-devel in Catalina for the first time in a few
weeks, and configure is dying with this error:
checking whether bzip2 support suffices... configure: error: bzip2
library and headers are required
I tried a Homebrew install of bzip2, and it didn't help.
When I look in config.log, I see this:
configure:45424: checking if bzip2 version >= 1.0.6
configure:45452: gcc -o conftest -g -O2 -I/usr/local/opt/libffi/include
-L/usr/local/opt/libffi/lib conftest.c -lbz2 -lz -licucore -ldl -lm
-liconv >&5

1 warning and 2 errors generated.
Suggestions for fixing this?
