[squid-users] Compiling squid-3.1.15 + openssl 1.0.0c

Dear squid users,

I am trying to compile squid from source, using 3.1.15 and openssl
1.0.0c...

Server: RedHat 5.5 x86_64
GCC version is 4.1.2

Error: (make)

/usr/local/src/squid-3.1.15/src/ssl/gadgets.cc:108: undefined reference

Squid 3.1.10 is working ok in the same box with openssl 1.0.0c, also
from source.

Any idea would be welcome.

Thank you in advance for your help.
