>Description:
	Can't build perl module written by C++ with perl 5.8.8nb1.
	With perl 5.8.7, it was OK.

>How-To-Repeat:

	For example, in pkgsrc-wip:

% cd /usr/pkgsrc/wip/p5-mecab
% make
===> Checking for vulnerabilities in p5-mecab-0.91
=> Checksum SHA1 OK for mecab-perl-0.91.tar.gz.
=> Checksum RMD160 OK for mecab-perl-0.91.tar.gz.
===> Extracting for p5-mecab-0.91
===> Required installed package mecab>=0.90: mecab-0.91 found
===> Required installed package mecab-base>=0.90: mecab-base-0.91 found
===> Required installed package perl>=5.8.7: perl-5.8.8nb1 found
===> Patching for p5-mecab-0.91
===> Overriding tools for p5-mecab-0.91
===> Creating toolchain wrappers for p5-mecab-0.91
===> Configuring for p5-mecab-0.91
Checking if your kit is complete...
Looks good
