Last I did a full Configure (5.001n) I noticed that specifying something
like /opt/perl5.001n/ didn't automatically make it use

/opt/perl5.001n/bin/
/opt/perl5.001n/lib/
/opt/perl5.001n/man/
/opt/perl5.001n/man/man1/
/opt/perl5.001n/man/man3/

which is what you probably would want.

If the path gets too long

/sun/export/sunos/sparc/opt/experimental/perl/bin/

than that's a problem too, which will have to be checked. Sigh.

That's fine by me. I just used very lightly modified versions of
the standard metaconfig units. I figured someone would want to do this.

It does now.

I vividly agree!!!!

====================
On the contrary!
====================

We do exactly the same:

Installing under /opt/packages/tools/perl5.001m/bin
/lib
/man
etc.

but symlink in /opt/bin/perl5 --> ../packages/tools/perl5.001m/bin/perl5

so that the shebang is always #!/opt/bin/perl5 even if the path to the
perl distribution is changed and the symlinks are rearranged!!

Since this is not supported by the current versions of the Perl distribution
I had to edit all the scripts in the perl/bin subdirectory by hand (I couldn't
automate this because there were not only shebangs but also perl variables
containing the path that had to be adapted).

So I think that an additional prompt for the #!-line to use would be a very
good idea!

Hear, hear. The same for us: perl might be installed under

/v/osf32_alpha/lang/perl/5.001m
/v/hpux9_hp700/lang/perl/5.001m
/v/aix32_rs/lang/perl/5.001m

depending on the architecture (the installer view) but I would like
the shebang on the pod2man etc. to be

#!/bin/perl

(the locally cached, on-the-local-disk, version of the one in /v/.../bin)

You shouldn't need to do all that work. I simply edited the config.sh file
and changed perlpath to the right value before the files were extracted.

Whimper. That's too long for #! to work on
many machines. :-( You only get 32 bytes,
minus the #! and maybe the args. Does Configure
check for that??

No, not presently.

Well, what about
compress=''
in the config.sh? There is no code to get anything else in
Configure. Can we check for gzip? This may help make better default
for MakeMaker's dist.
