compilation troubles

Hello,

When i try to compile postgreSQL with --enable-multibyte=KOI8

Then run 'gmake'
Compilations stops on:

gcc -pipe -O2 -Wall -Wmissing-prototypes -Wmissing-declarations -I../../../src/include   -c -o pg_encoding.o
pg_encoding.c
gcc -pipe -O2 -Wall -Wmissing-prototypes -Wmissing-declarations pg_encoding.o -L../../../src/interfaces/libpq -lpq
-R/usr/local/pgsql/lib-lz -lcrypt -lcompat -lm -lutil -lreadline  -o pg_encoding 
pg_encoding.o: In function `main':
pg_encoding.o(.text+0x3d): undefined reference to `pg_char_to_encoding'
pg_encoding.o(.text+0x7c): undefined reference to `pg_encoding_to_char'
gmake[3]: *** [pg_encoding] Error 1


What is this? How can i solve this problem?
