Thanks to the guys of the sqlcipher project this has been resolved: I went by the tutorial on the sqlcipher.net site rather than reading the README ;)
Speaking - put everything in place, go with the good old command prompt in the sqlcipher root directory and set off the following:
$ ./configure --enable-tempstore=yes CFLAGS="-DSQLITE_HAS_CODEC" \
LDFLAGS="-lcrypto"
$ make
This builds the missing files and you're ready to build the whole thing!
