 Replying to [comment:6 jmr@…]:
 > Actually I do see this for the ports you mention, but not for all ports
 with an underscore in the version.
 I believe I have identified the issue.  It's the underscore '''and the
 dash''' in "2.2_20050523-0".  iozone's version is 3_373, which has no
 dash.

 Now, look at proc decode_spec
 (/opt/local/share/macports/Tcl/registry2.0/registry_util.tcl:55):

 {{{
 proc decode_spec {specifier version revision variants} {
     upvar 1 $version ver $revision rev $variants var
     return [regexp {^([^+]+?)(_(\d+)(([-+][^-+]+)*))?$} $specifier - ver -
 rev v
 ar]
 }
 }}}

 Experimenting interactively with that regexp:

 {{{
 $ tclsh
 % echo [regexp {^([^+]+?)(_(\d+)(([-+][^-+]+)*))?$} "2.2_20050523-0_0" -
 ver - rev var]
 1
 % echo $ver
 2.2
 % echo $rev
 20050523
 % echo $var
 -0_0
 % echo [regexp {^([^+]+?)(_(\d+)(([-+][^-+]+)*))?$} "3_373_0" - ver - rev
 var]
 1
 % echo $ver
 3_373
 % echo $rev
 0
 % echo $var

 %
 }}}
