library clash: system vs. ports. What to do?

[Rob]

Hello,

This is on 4-Stable. When I run "portsclean -L", I get:

** /usr/local/lib/libcrypto.so.3 is shadowed by /usr/lib/libcrypto.so.3
         /usr/lib/libcrypto.so.3 <- ?
         /usr/local/lib/libcrypto.so.3   <- openssl-0.9.7d_1
  --> This may be an undesirable situation
Leave /usr/lib/libcrypto.so.3 (specify -i to ask on this)

** /usr/local/lib/libssl.so.3 is shadowed by /usr/lib/libssl.so.3
         /usr/lib/libssl.so.3    <- ?
         /usr/local/lib/libssl.so.3      <- openssl-0.9.7d_1
  --> This may be an undesirable situation
Leave /usr/lib/libssl.so.3 (specify -i to ask on this)

** /usr/local/lib/libgssapi.so.5 is shadowed by /usr/lib/libgssapi.so.5
         /usr/lib/libgssapi.so.5 <- ?
         /usr/local/lib/libgssapi.so.5   <- heimdal-0.6.1
  --> This may be an undesirable situation
Leave /usr/lib/libgssapi.so.5 (specify -i to ask on this)

The libraries are different (at least different size), despite
equal names. Is this indeed an undesirable situation ?
If so, what am I supposed to do in this case?
Will I break the system when removing the one in /usr/lib ?
Will I break the port when removing the one in usr/local/lib ?

So far I have left all in place, without encountering any problems yet.

Rob.
