PCRE is the library on which the command "regexp" is based (as far as  
I understand).
On ubuntu I think this is located /usr/lib/libpcre.so
my guess whas that, maybe due to missing/malfunctioning libpcre
the regexp command in your Octave is not working properly so that the
call to regexp in __gnuplot_version__ returns "4.2."
instead of "4.2" or "4.2.2" which would be valid version strings
