Error on XStreamOS/illumos (SunOS 5.11)

[gbulfon]

Hi, I'm trying to package and distribute the script on our XStreamOS/illumos distro (SunOS 5.11).
Running the script the first time with "--force" I get this error:

/sonicle/sbin/clamav-unofficial-sigs.sh: line 1849: --reload: command not found

Looks like the problem is here:

eval 'setmode=yes clam_dbs=/var/lib/clamav clamd_pid=/var/run/clamav/clamd.pid reload_dbs=yes clamd_reload_opt=clamdscan --reload work_dir=/var/lib/clamav-unofficial-sigs'

where clamd_reload_opt is set without apices, so it takes "--reload" as a separate command (output from bash -x):

++ setmode=yes
++ clam_dbs=/var/lib/clamav
++ clamd_pid=/var/run/clamav/clamd.pid
++ reload_dbs=yes
++ clamd_reload_opt=clamdscan
++ --reload work_dir=/var/lib/clamav-unofficial-sigs

What's wrong? I used Solaris 11 OS config file with few changes based on my system.

Thanks,
Gabriele
