Description Juergen Rose 2012-08-27 09:18:15 UTC
'emerge -uvDN world' wants to upgrade perl-gcpan/Math-GSL to version 0.27.
Math-GSL tries then to install several other perl-gcpan packages, which are already installed as dev-perl packages:

root@condor:/usr/local/portage/media-tv(136)# emerge -pvuNDt world

These are the packages that would be merged, in reverse order:

On my other systems the update to perl-gcpan/Math-GSL-0.27 works without problems. Any idea, what could be the reason of this strange behaviour? And how can I circumvent it? I can deinstall perl-gcpan/Math-GSL, then 'emerge -uvDN world' works again witout problems. But the next 'emerge -vuND Math-GSL' fails again, because it tries again these perl-gcpan packages:

root@condor:/usr/local/portage/sys-power/apcupsd(195)# emerge -pvuND Math-GSL

These are the packages that would be merged, in order:

Comment 1 Juergen Rose 2012-08-27 12:58:10 UTC
At systems where Math-GSL-0.27 is installed the dependency generated by g-cpan is:

DEPEND=">=dev-perl/Test-Exception-0.310.0
	>=dev-perl/Test-Class-0.360.0
	dev-perl/Test-Most
	dev-perl/extutils-pkgconfig
	dev-lang/perl"

and at the systems, where the installation fails, it is:
 
DEPEND=">=perl-gcpan/Test-Exception-0.31
	>=perl-gcpan/Test-Class-0.37
	perl-gcpan/Test-Most
	dev-perl/extutils-pkgconfig
	dev-lang/perl"
Comment 2 Juergen Rose 2012-08-27 13:04:53 UTC
If I delete the /var/lib/cpan/perl-gcpan/Math-GSL directory at the affected system and recreate it with g-cpan -i Math-GSL, then the created 
Math-GSL-0.27.ebuild has again:

DEPEND=">=perl-gcpan/Test-Exception-0.31
	>=perl-gcpan/Test-Class-0.37
	perl-gcpan/Test-Most
	dev-perl/extutils-pkgconfig
	dev-lang/perl"
Comment 3 Juergen Rose 2012-08-29 07:53:43 UTC
I also tried a complete new installation of Math-GSL on a system where Math-GSL was never installed. Again /var/lib/cpan/perl-gcpan/Math-GSL/Math-GSL-0.27.ebuild contains:

DEPEND=">=perl-gcpan/Test-Exception-0.31
	>=perl-gcpan/Test-Class-0.37
	perl-gcpan/Test-Most
	dev-perl/extutils-pkgconfig
	dev-lang/perl"

and 'g-cpan -i Math-GSL' fails with:

Comment 4 Juergen Rose 2012-09-01 12:49:24 UTC
I found the same error on two further systems. It looks for me if g-cpan with perl-5.16.1 does not recognize that there are dev-perl packages and that's why generate ebuild with dependencies on perl-gcpan packages:

root@orca:/root(1)# emerge -pvD Math-GSL

These are the packages that would be merged, in order:

perl-gcpan/Math-GSL-0.27 was built with the following:
USE="(multilib)"
Comment 9 is 2013-03-05 09:54:35 UTC
I have seen similar things with other packages, the most recent being perl-gcpan/IPC-Run-0.92 and dev-perl/IPC-Run-0.920.0. Others were of the Test-XXX family, sorry I forgot which ones. 

The perl-gcpan variants were all pulled in as dependencies while the dev-perl ones were already installed. I could guess perl-gcpan fails to recognise them because of different version strings? Anyways, this is pretty annoying.
