hardwired perl

[Karl Berry]

Patrice,

I think the problems on my netbsd are all about finding perl, and the
bottom line is that run_parser_all.sh, etc., need to use the value of
@PERL@ which configure found, rather than assuming "perl" is in PATH.
As in line 239:
eval "$prepended_command perl -w -I ...

I set PATH=/bin:/usr/bin, which does not include perl on this machine,
and did configure PERL=/usr/local/bin/perl.

Actually worrying about the case when perl is not in PATH isn't so
important IMHO, but I think it is important to consistently use the
same perl for all phases of the build/check/run, otherwise we will
surely run into problems where different perls have different libraries,
or whatever.

I'll try to work on this later today if you don't get to it first.

Thanks,
k
