For versions 2.1.0 and above you may need a custom installation of sqlite:

wget http://www.sqlite.org/2013/sqlite-autoconf-3080200.tar.gz
tar -xzf sqlite-autoconf-3080200.tar.gz
cd sqlite-autoconf-3080200/
./configure --prefix=/path/to/sqlite --host=powerpc64-bgq-linux CC=mpicc LDFLAGS=-dynamic
sed -e's|sqlite\\\\ |sqlite_|g' -i config.status
make && make install

When installing Sherpa, use the following configure options

./configure <your options> --enable-mpi --with-sqlite3=/path/to/sqlite --host=powerpc64-bgq-linux CC=mpicc CXX=mpic++ FC='mpif90 -fPIC -funderscoring' LDFLAGS=-dynamic

Note that SQLite locking is broken on BG/Q. To work around this problem, please use ​the patch below and run Sherpa with commandline option

SQLITE_OPEN_FLAG=unix-none

which can also be put into the (run) section of your input file.
