Search by contents in GWorkspace

[Gebhart, Mark A]

Hi,
I am running Gworkspace .4.1 and can not get the search by contents feature to work correctly. It gives me the following error:

xargs: illegal option --r
Xargs: usage:xargs: [-t][-p][-e[eofstr]][-E eofstr][-I replstr] [-i[replstr]][-L #] [-l [#]][-n # [-x]][-s[size][cmd[args . . . ]]

My system is as follows:
Gcc 3.1
Solaris 2.8
Back 0.8.4
Base 1.5.2
Gui 0.8.4
Make 1.5.2
GNU Window Manager 0.80.0

Any help would be greatly appreciated.
Thanks,
Mark
