## Known installation issues
* On CentOS, if you are using a more modern `devtoolset`, you may need to set
-the environment variables `CC=/usr/bin/gcc CXX=/usr/bin/g++`.
-See discussion [here](https://issues.apache.org/jira/browse/ARROW-8586).
+the environment variables `CC` and `CXX` either in the shell or in R's
`Makeconf`.
+For CentOS 7 and above, both the Arrow system packages and the C++ binaries
+for R are built with the default system compilers. If you want to use either
of these
+and you have a `devtoolset` installed, set `CC=/usr/bin/gcc CXX=/usr/bin/g++`
+to use the system compilers instead of the `devtoolset`.
+Alternatively, if you want to build `arrow` with the newer `devtoolset`
compilers,
+set both `ARROW_USE_PKG_CONFIG` and `LIBARROW_BINARY` to `false` so that
+you build the Arrow C++ from source using those compilers.
+Compiler mismatch between the arrow system libraries and the R
+package may cause R to segfault when `arrow` package functions are used.
+See discussions [here](https://issues.apache.org/jira/browse/ARROW-8586)
+and [here](https://issues.apache.org/jira/browse/ARROW-10780).
* If you have multiple versions of `zstd` installed on your system,
installation by building the C++ from source may fail with an undefined symbols
