OpenSSH pkgadd installation

[Wiese, Maria]

I am having a problem installing the OpenSSH package in one of my servers
running Solaris 2.6. 
The pkgadd fails  with the following error messages:
/usr/local/bin/ssh-keygen: syntax error at line 6: ')' unexpected. 
ERROR: attribute verification of </usr/local/etc/ssh_host_dsa_key> failed.

The same failure for all other keys. 

The server is a sparc4  (sun4M) .   
I installed the same pakcages in 2 other servers with no problem.

Can  you please help me identify the problem?
