ascii_and_mic.so - Mailing list pgsql-bugs

i cannot compile your last release of postgresql (7.3.2). i'm using right
now the 7.2.1 on a red hat 7.3.

if you could help me find the problem :
gmake check

install:
/var/tmp/postgresql-7.3.2/src/test/regress/./tmp_check/install/usr/lib/postg
resql/ascii_and_mic.so does not exist

what is this ascii_and_mic.so - where can i find this?
