We are open to suggestions about how to re-write any of this. One might
imagine doing:
$ IF F$TRNLNM("PERL_ROOT") .NES. "" THEN dflt = F$TRNLNM("PERL_ROOT")
however, that could lead to trouble if you did not do:
$ delete perl_root:[000000...]*.*;*
before your `mms install` step (the scenario I have in mind is picking
up an older version of a module that gets installed on the later version
of perl on VMS in a place where the @INC array sees the prior version
before the later version).
The current way of setting the default $prefix value is based on the older
notion that there was no installperl script that worked on VMS. One might
argue that setting perl_root to some place in SYS$LIBRARY would be the
proper "dflt" for VMS, although anyone who wanted to install perl without
write access to SYS$LIBRARY would then be forced to specify
"-Dprefix=MY:[PRIVATE_INSTALL.]" and they currently do not have to do so
(if you were able to unpack the tar ball then you at least have write
access to the build location).
