ghc-6.8.3 fail to install.

[Loïc Maury <lmaury%gmail.com@localhost>]

Hello,

I try to instal ghc, but in the configure step, it say :

checking for perl... /usr/pkgsrc/lang/ghc/work/.tools/bin/perl
configure: error: your version of perl probably won't work, try upgrading it
*** Error code 1

I think I have the last version of perl (v5.14.1)

I don't know how I can fix this issue ?

Thanks

Loïc
