Fail during configure if perl is missing but required about curl

[bagder]

I believe this is fixed in git already. Can you test a recent daily snapshot?

Tried latest, doesn't build:

I won't have time to bisect the first working nightly daily snapshot, unfortunately.

Try nuking the directory and starting again. That issue can happen if some old files from a failed build are still lying around.

[bagder]

I second @dfandrich's proposal. hugehelp is a function that should exist whether perl is present or not.

Happens consistently on 2024-03-28 and 2024-04-30 on Alpine Linux using the Spack package manger. Dependency graph looks like this:

Earlier the error is:

/bin/sh: can't open /tmp/root/spack-stage/spack-stage-curl-20240328-y2ewq45hp2dhrks6otovqizdxiozsdo3/spack-src/docs/cmdline-opts/curl.txt: no such file
/bin/sh: can't open /tmp/root/spack-stage/spack-stage-curl-20240328-y2ewq45hp2dhrks6otovqizdxiozsdo3/spack-src/docs/cmdline-opts/curl.txt: no such file

EDIT*

🤦‍♂️ the --disable-docs flag had gone missing while adding new versions. All is good when I add the flag back for both versions tested.

Would be convenient though if curl failed during configure if perl is required and missing...
