 some more information related to this issue:
 The error appears to only occur when the "rrdtool graph" function is
 invoked via the perl module RRDs and when embedded in an apache web
 server, with an embedded perl interpreter.
 A plain command with "rrdtool graph <args>" where the args are
 as specified by the web server script results in no error.
 Also, a simple perl script replicating what the web server does using
 RRDs::graph() with the same args also does not return any error.
 I've looked in /usr/pkg for files containing the string pcre_config,
 but did not find any occurrances which would indicate there's a symbol
 conflict for that name.
 Some of the changes introduced between rrdtool 1.4.8 and 1.4.9 is that
 a homebrew and possibly incomplete regexp matcher was replaced with
 use of the glib2 regexp wrapper functions using pcre (g_regex_new() /
 g_regex_match()).  When embedded as described above, these calls fail,
 while they succeed when run either standalone (via rrdtool) or under a
 non-apache-embedded perl.
 Hints for further debugging welcome.
