But same error.

Build Perl for SOCKS? [n]
Use the PerlIO abstraction layer? [y]
Getting the current patchlevel...
Build a threading Perl? [n]
Build Perl for multiplicity? [n]
Use which C compiler? [cc]
/usr/lib/libpthread.so: undefined reference to `__pselect at FBSDprivate_1.0'
Uh-oh, the C compiler 'cc' doesn't seem to be working.
You seem to have a working gcc, though.
Would you like to use it? [y]
/usr/lib/libpthread.so: undefined reference to `__pselect at FBSDprivate_1.0'
You need to find a working C compiler.
Either (purchase and) install the C compiler supplied by your OS vendor,
or for a free C compiler try http://gcc.gnu.org/
I cannot continue any further, aborting.
===>  Script "Configure" failed unexpectedly.
Please report the problem to perl at FreeBSD.org [maintainer] and attach the
"/usr/ports/lang/perl5.14/work/perl-5.14.2/config.log" including the output
of the failure of your make command. Also, it might be a good idea to provide
an overview of all packages installed on your system (e.g. a /usr/sbin/pkg_info
-Ea).
*** Error code 1

Stop in /usr/ports/lang/perl5.14.
