Please run the following command to find out where the `Scalar/Util.pm` is being loaded from, and if the corresponding `Util.so` is found: `$ PERL_CORE=1 tusc ./perl ext/Storable/t/weak.t \| grep Util` [download] This must be run from the main build directory, where the perl binary is located.

Please run the following command to find out where the Scalar/Util.pm is being loaded from, and if the corresponding Util.so is found:

$ PERL_CORE=1 tusc ./perl ext/Storable/t/weak.t | grep Util
[download]

This must be run from the main build directory, where the perl binary is located.

The normal output from this - with a fully functioning Scalar::Util - would look like this:

stat64("./Scalar/Util.pmc", 0x7fffdf30) ............. ... ERR#2 ENOENT
stat64("./Scalar/Util.pm", 0x7fffdeb0) .............. ... ERR#2 ENOENT

open("../lib/auto/List/Util/Util.so", O_RDONLY, 0) .. ... = 4
open("../lib/auto/List/Util/Util.so", O_RDONLY, 0) .. ... = 4
[download]

In case you don't get any output, make sure you can run the test itself (without tusc), i.e.

$ PERL_CORE=1 ./perl ext/Storable/t/weak.t
[download]

Alternatively, you could try to just load the module Scalar::Util and import weaken (output should be similar to above):

$ tusc ./perl -I./lib -MScalar::Util=weaken -e1 | grep Util
[download]

And if you find that you do have a Util.so, you might want to check whether it has been compiled properly (contains the required symbols):

$ nm ./lib/auto/List/Util/Util.so | grep weak                         
+

Also (just in case) you could check for other perls:

$ find /opt/perl* -path "*bin/perl"

$ find /opt/perl* -path "*bin/perl" -exec {} -v \; | grep 'is perl'
[download]

...because at least the code from Perl's Configure, which populates @inc_version_list, apparently did find directories for versions from 5.8.0 all through to 5.8.7. This doesn't necessarily mean that all those are full installations, but it's at least a hint that there are - or have been - other versions of Perl on that machine, which might interfere under some circumstances (like PERL5LIB being set)...
