ghcup-0.1.22.0 with libtinfow.so.9 currently broken on FreeBSD

[mr0mr0]

ghcup-0.1.22.0 (as fetched by curl) fails to run on FreeBSD owing to a linker error for versioned shared object "libtinfow.so.9".
FreeBSD install of ncurses currently delivers libtinfo.so.6
Previous version ghcup-0.1.20.0 does not exhibit this problem, and runs okay on FreeBSD
Attempts to hack the shell script delivered by curl, eg by setting script environment variable "ghver=0.1.20.0", fail owing to immediate auto-upgrade to the the non-working version

Workaround:
[1] run the script from curl as far as possible to get some .ghcup infrastructure in place (it ends with the linker error as below)
[2] over-write ghcup with the earlier version
ghver="0.1.22.0"; curl -Lf "https://downloads.haskell.org/~ghcup/$ghver/x86_64-portbld-freebsd-ghcup-$ghver" >~/.ghcup/bin/ghcup
chmod a+x ~/.ghcup/bin/ghcup
[3] ghcup tui # now works for me

libtinfow.so.9 is provided by the FreeBSD base system and it is SONAME 9 for FreeBSD 14: https://github.com/freebsd/freebsd-src/blob/stable/14/lib/ncurses/tinfo/Makefile#L10

We do not actively support older FreeBSD versions. Which version are you running?

[mr0mr0]

D'oh! back to school for me! I am lurking behind the curve on FreeBSD 13.2
I like your idea: "OS is older than currently GHCup supported version - consider this in case of problems"
My apologies, and thanks for checking.

[hasufell]

I would like to support even older FreeBSDs and I have private CI that can do that with pots/jails.

But it's work and I do all this in my free time anyway.
