portupgrade: complete failure due to devel/apr-svn

[Jan Henrik Sylvester]

After refreshing all packages in /usr/ports/packages/All, I tried to 
upgrade all ports on a machine that had the last 'portupgrade -a' a few 
month (?) ago. I got:

# portupgrade --batch -PP -x openoffice.org -a
** Port marked as IGNORE: devel/apr-svn:
                  at line 1115 (evaluated to true)
** Proceeding anyway since NO_IGNORE is defined
/usr/local/lib/ruby/site_ruby/1.8/pkgversion.rb:41:in `initialize': : 
Not in due form: '<version>[_<revision>][,<epoch>]'. (ArgumentError)

         from /usr/local/sbin/portupgrade:613:in `main'
         from /usr/local/sbin/portupgrade:588:in `catch'
         from /usr/local/sbin/portupgrade:588:in `main'
         from /usr/local/lib/ruby/1.8/optparse.rb:1303:in `call'
         from /usr/local/lib/ruby/1.8/optparse.rb:1303:in `parse_in_order'
          ... 7 levels...
         from /usr/local/lib/ruby/1.8/optparse.rb:785:in `initialize'
         from /usr/local/sbin/portupgrade:229:in `new'
         from /usr/local/sbin/portupgrade:229:in `main'
         from /usr/local/sbin/portupgrade:2173

Examining the ports, I do not see where the IGNORE of devel/apr-svn 
comes from. Moreover, I have not found a clue about the cause of the 
second error message searching for it.

I did "upgrade" devel/apr-svn manually with 'pkg_delete -f 
apr-db42-1.2.8_2', 'pkg_add apr-gdbm-db42-1.2.8_3.tbz', and 'pkgdb -s 
/apr-db42-1.2.8_2/apr-gdbm-db42-1.2.8_3/'. That did not change the 
outcome. '-x devel/apr-svn' did not help portupgrade, either.

portupgrade was current (portupgrade-2.4.3_2,2) and ruby, too 
(ruby-1.8.6.111_1,1).

Any idea what is wrong or how to fix it?

Thanks,
Jan Henrik
