Problem building security/putty on Linux

[Iain Morgan <Iain.Morgan%nasa.gov@localhost>]

Hello,

Trying to build security/putty on an RHEL 6.5 system, using cvs HEAD,
fails due to multiple undefined references to dlsym, dlopen, dlcose, etc.
I'm a little perplexed as to hey this is happening, given that USE_BUILTIN.dl
is set to 'yes'.

Running the build under script and then grep'ing for -ldl finds no
matches. Likewise, 'bmake show-var VARNAME=DL_LIBS' returns an empty
line.

Regards,
