+Made these changes to IkiWiki/Wrapper.pm:
+
+````
+        my @envsave;
+        push @envsave, qw{REMOTE_ADDR QUERY_STRING REQUEST_METHOD REQUEST_URI
+                       CONTENT_TYPE CONTENT_LENGTH GATEWAY_INTERFACE
+                       HTTP_COOKIE REMOTE_USER HTTPS REDIRECT_STATUS
+                       HTTP_HOST SERVER_PORT HTTPS HTTP_ACCEPT
+                       REDIRECT_URL} if $config{cgi};
+        push @envsave, qw{GIT_OBJECT_DIRECTORY GIT_QUARANTINE_PATH
+                       GIT_ALTERNATE_OBJECT_DIRECTORIES} if $config{test_receive};
++        push @envsave, qw{PERL5LIB};
+        my $envsave=\"\";
+        foreach my $var (@envsave) {
+                $envsave.=<<\"EOF\";
+        if ((s=getenv(\"$var\")))
+                addenv(\"$var\", s);
+EOF
+        }
+
+
+````
+
+and this:
+
+```
+$check_commit_hook
+@wrapper_hooks
+$envsave
+        addenv(\"HOME\", \"$ENV{HOME}\");
+        addenv(\"PATH\", \"$ENV{PATH}\");
++        addenv(\"PERL5LIB\", \"$ENV{PERL5LIB}\");
+        addenv(\"WRAPPED_OPTIONS\", \"$configstring\");
+```
+
+I don't know which of the two changes was needed - maybe only one. Now it builds. :-)
