+You can use "Configure -Uinstallusrbinperl" which causes installperl

By default, Configure will compile perl to use dynamic loading if
your system supports it. If you want to force perl to be compiled
statically, you can either choose this when Configure prompts you or

+Note that Perl's malloc family of functions are called Perl_malloc(),

=head2 Malloc Performance Flags
If you are using Perl's malloc, you may add one or more of the following
Undefined by default. Defining it in addition to NO_FANCY_MALLOC returns
malloc to the version used in Perl version 5.000.
+=item -DPERL_POLLUTE_MALLOC
+
+Undefined by default. This is used to force Perl's malloc family of functions
+to have the same names as the system versions. This is normally only required
+when you have a need to replace the system versions of these functions.
+This may be sometimes required when you have libraries that like to free()
+data that may have been allocated by Perl_malloc() and vice versa.
+
+Note that enabling this option may sometimes lead to duplicate symbols from
+the linker for malloc et al. In such cases, the system probably does not
+allow its malloc functions to be fully replaced with custom versions.
