 Hi,

 I'm creating a Portfile which contains several subports.

 I would like to add these subports as a dependency of my main Portfile,
 but it seems not possible.
 When I try to install I have the following error.

 {{{
 --->  Dependencies to be installed: py-bob.blitz py-bob.core py-
 bob.io.base
 Error: The following dependencies were not installed: py-bob.blitz py-
 bob.core py-bob.io.base
 }}}

 Those packages "py-bob.blitz py-bob.core py-bob.io.base" are my subports.
 The dependencies are defined in the line 64 of the attached file.

 Thank you very much in advance!!

Comment:

 In the Portfile you've written

 {{{
 depends_run \
     port:py-bob.blitz \
     port:py-bob.core \
     port:py-bob.io.base
 }}}

 outside of any blocks or conditionals. That means it applies to all ports,
 both the "main" port and all the subports. So, for example, you've asked
 the subport py-bob.blitz to have a dependency on itself, which of course
 can't work. If you only want the main port to have those dependencies, say
 that:

 {{{
 if {${subport} eq ${name}} {
     depends_run \
         port:py-bob.blitz \
         port:py-bob.core \
         port:py-bob.io.base
 }
 }}}

 But there are additional problems here. You're using the python portgroup,
 whose purpose is to let you create one port (named py-''something'') and
 it will create subports for you (named py26-''something'',
 py27-''something'', py33-''something'', py34-''something'', etc.) based on
 how you set `python.versions`. But then you're trying to create additional
 py-''somethingelse'' subports as well. The python portgroup doesn't know
 anything about these other subports you've created, and will not create
 py26-''somethingelse'' etc. subports for you, so that won't work right.
 Furthermore, these subports are all for different software, which have
 their own version numbers, master_sites, distfiles and checksums. I think
 you'll find things will work correctly if you create a separate portfile
 for each software, and not try to put them all into the same portfile.

 If you need further help developing portfiles, please write to the
 macports-dev mailing list rather than filing tickets in the issue tracker.
