contrib module soundex in CVS snapshot (function returning text and TOAST ???)

Hi all,
I've just downloaded the latest CVS snapshot, to play with
TOASTed text field. I've tried to compile contrib extensions
but I've some problem with soundex.

I take

gcc -c -I../../src/include -O2 -Wall -Wmissing-prototypes
-Wmissing-declarations -I. -fpic soundex.c -o soundex.o
soundex.c: In function `text_soundex':
soundex.c:37: invalid lvalue in assignment
make: *** [soundex.o] Error 1

text_soundex() is declared as

text *
text_soundex(text *t)

perhaps the interface is changed with TOAST.

Any FAQ pointer to help me in this case ???
TIA
