+Recently, while compiling latest Rust version I came across a problem on my very
+old Macbook where `emerge` complained about not enough RAM to compile Rust.
+
+The `check-reqs_pkg_setup` from `check-reqs.eclass` takes care of this check:
+
+```bash
+...
+pre_build_checks() {
+    CHECKREQS_DISK_BUILD="7G"
+    CHECKREQS_MEMORY="4G"
+...
+    check-reqs_pkg_setup
+}
+```
+
+If you don't have enough memory, the quick and dirty solution is to add enough
+swap and run `emerge` again with `${I_KNOW_WHAT_I_AM_DOING}` set.
+
+```
+fallocate -l 8G /mnt/swap.swap
+mkswap /mnt/swap.swap
+swapon /mnt/swap.swap
+chmod 600 /mnt/swap.swap
+I_KNOW_WHAT_I_AM_DOING=1 emerge -1 rust
+```
