 The file /opt/local/lib/perl5/vendor_perl/5.34/ExtUtils/Embed.pm comes
 from the port p5.34-extutils-embed. This port is not listed as a
 dependency of mod_perl2. Maybe mod_perl2 conflicts with it. Try
 deactivating that port first. Clean mod_perl2 before trying again.

 p5.34-extutils-embed seems to be confused about its version number. The
 port version is 1.140.0 but the code in the file that calculates its
 version is written as:

 {{{
 $VERSION = sprintf("%d.%02d", q$Revision: 1.2505 $ =~ /(\d+)\.(\d+)/);
 }}}

 hence it is reporting its version as 1.2505.

 The ExtUtils::Embed module appears to be part of the perl core. The
 perl5.34 port provides a newer version of this module at
 /opt/local/lib/perl5/5.34/ExtUtils/Embed.pm which I assume will be used if
 the separate older module is not installed. I wonder how long it has been
 part of the perl core and whether there is still any good reason for us to
 have a separate port for it. We do still have some very old perl versions
 available in MacPorts though (perl5.16 is the oldest); maybe it is still
 useful for those.
