If you upgrade to perl5.001m, which is the current stable version,
this is taken care of. At least, flock() will be emulated if need
be. I'm curious though why it isn't finding the normal version in
flock(3B) on Solaris. CC'd to porters for their consideration.

Because . doesn't match \n. [\0-\377] is the most efficient way to match
everything currently. Maybe \e should match everything. And \E would
of course match nothing. :-) --Larry Wall in <9847@jpl-devvax.JPL.NASA.GOV>

As the user mentions, flock(3B) is part of the BSD compatability package.
In general, the bsd (or -lucb) stuff doesn't mix well with the SVR4 base
of Solaris. I think the man page for flock has more information on this.
