-    pacman -S git base-devel boost libevent python
+    pacman --sync --needed autoconf automake boost gcc git libevent libtool make pkgconf python sqlite
     git clone https://github.com/bitcoin/bitcoin.git

-Note:
-Enabling wallet support requires either compiling against a Berkeley DB newer than 4.8 (package `db`) using `--with-incompatible-bdb`,
-or building and depending on a local version of Berkeley DB 4.8. The readily available Arch Linux packages are currently built using
-`--with-incompatible-bdb` according to the [PKGBUILD](https://github.com/archlinux/svntogit-community/blob/packages/bitcoin/trunk/PKGBUILD).
-As mentioned above, when maintaining portability of the wallet between the standard Bitcoin Core distributions and independently built
-node software is desired, Berkeley DB 4.8 must be used.

+If you intend to work with legacy Berkeley DB wallets, see [Berkeley DB](#berkeley-db) section.
