Homebrew has given me some warnings and told me to delete certain files from both /usr and /Library folders, which are getting in the way certain installs. Is there a way to remove these files from the root directory, or do I have to manually
Warning: libiconv files detected at a system prefix other than /usr Homebrew doesn't provide a libiconv formula, and expects to link against the system version in /usr. libiconv in other prefixes can cause compile or link failure, especially if compiled with improper architectures. OS X itself never installs anything to /usr/local so it was either installed by a user or some other third party software. tl;dr: delete these files: /usr/local/lib/libiconv.dylib /usr/local/include/iconv.h
It also told me to delete another file
Warning: /Library/Frameworks/Mono.framework detected This can be picked up by CMake's build system and likely cause the build to fail. You may need to move this file out of the way to compile CMake.
