[gentoo-user] emerge dev-lang/perl-5.12.3 failed

[Kraus Philipp <philipp.kraus@flashpixx.de>]

Hello,

I've try to emerge my world target new, but the dev-lang/perl-5.12.3  
failes. I've found on the gentoo pages the hint to sync the portage  
tree again, but that does not solve the problem.

The messages during emerge are:

IO.xs: In function 'XS_IO__File_new_tmpfile':
IO.xs:229: warning: value computed is not used
IO.xs: In function 'XS_IO__Poll__poll':
IO.xs:249: error: invalid application of 'sizeof' to incomplete type

I've try to mask the 5.12.3 package to a previous version, but the  
same problemes are shown. Now I've have a "hanging" portage. Perl is  
needed for my eg. LDAP... Does anyone have any idea to solve the error?

Thanks

Phil
