In src/include/utils/elog.h there is an include for "utils/errcodes.h" 
which is generated somehow when compiling postgresql but not present by 
default. So you have to compile postgresql and then the contrib, or use 
PGXS with an already installed version.

With this caveat, the one-liner patch (4 characters removed) reattached 
does compile for me:
  sh> git branch ismn2  sh> git checkout ismn2  sh> patch -p1 < ~/ismn-checksum.patch  patching file contrib/isn/isn.c
sh>...  sh> cd contrib/isn  sh> make  gcc -O2 -Wall -Wmissing-prototypes -Wpointer-arith -Wdeclaration-after-statement
