>Description:

Building ghc on a 2.0 system fails with getpwnam_r and friends
undefined in the bootstrap stage:

/usr/pkgsrc/lang/ghc/work/ghc-boot/libraries/unix/libHSunix.a(User.o)(.text+0x18e9): In function `s3UR_ret':
: undefined reference to `getpwnam_r'

etc.

because these functions aren't in libc.

Examining checked-out 2.1-branch libc source shows that getpwnam_r
doesn't exist there either, although apparently it's been pulled up
into 3.x.

The problem appears to have been introduced with the new bootstrap kit
mentioned in -r1.31 of lang/ghc/Makefile on 20060731.

>How-To-Repeat:

Build ghc on a 2.0 or 2.1 system.

>Fix:

Reverting to the previous pkgrevision (6.4.2nb2) of 20060730 serves as
an adequate workaround for now.

I don't know what the right fix is; unfortunately, fiddling with the
ghc build is a heavily time-intensive process.

One could also pull getpwnam_r and friends up into the 2.x branches,
but that's probably a can of worms.
