mcrypt-2.5.5 compile prob

[Anon]

Hello all,

Any suggestions for this?

I'm running Red Hat Linux release 6.1 (Cartman) Kernel 2.2.14 on an i686 and trying to configure and compile mcrypt-2.5.5. The libmcrypt-2.4.10 requires this and the mhash-0.7.0. These later two I had no problem with config and compile.
Config works ok with mcrypt-2.5.5 but when I try to compile it, this is the error:

keys.c: In function `mcrypt_gen_key':
keys.c:35: `KEYGEN' undeclared (first use in this function)
keys.c:35: (Each undeclared identifier is reported only once
keys.c:35: for each function it appears in.)
keys.c:35: parse error before `data'
keys.c:54: `data' undeclared (first use in this function)
make[2]: *** [keys.o] Error 1
make[2]: Leaving directory `/usr/lib/apache/mcrypt-2.5.5/src'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/usr/lib/apache/mcrypt-2.5.5'
make: *** [all-recursive-am] Error 2

Here's line 35 for keys.c:
KEYGEN data;
and line 54:
data.hash_algorithm[0] = algo;

Why is the bombing out?
Any help please??
Thank you,
gary
