nsca/mcrypt problem on Solaris 10

[JDB]

Hi,

I have installed nagios 3.0.6 and nsca-2.7.2 along with mcrypt-2.5.8 (CSWlibmcrypt) on a solaris 10 i386 box, and all the compilation went well, but whenever I run the test script that uses send_nsca I get the following client error :

Error: Server closed connection before init packet was received
Error: Could not read init packet from server

A server error appears in /var/adm/messages:
Jul 11 13:06:19 rozrhappt01-mont nsca[13793]: [ID 334271 daemon.error]
Could not open mcrypt algorithm 'blowfish' with mode 'cfb'

Other crypto algorithms fail in the same way.
However, the test works with plain XOR option=1.

Other info
$ uname -a
SunOS nagios-server 5.10 Generic_144489-04 i86pc i386 i86pc

Can anyone help me out, please.

Problem solved.
The root cause was a "toxic mcrypt package" on my Nagios server, apparently an unstable release from Blastwave.
My solution is replacing this package with an earlier release from the stable tree.
Sad the Blastwave is not so active any more.

Toxic package:

Note that this was occurred when compiling ncsa & send_ncsa from source.
This problem can be skipped by installed the CSW/Blastwave packages:
