When asking for help, you need to supply the system you're encountering 
the problem on, because the fix is very different depending on if you're 
running Solaris, IRIX, AIX, BSD or Linux (or Windows, for that matter, 
although I'm fairly certain you'd run into unsurmountable problems on 
such an un-posixy platform).

This happens because gcc doesn't link in the dynamic link loader in the 
program itself. Since this is a compiling issue you'll also need to 
supply the compiler and linker version (gcc --version and ld --version 
should work with GNU tools).

The problem seems to stem from the fact that you've installed the 
statically linked version of openssl but still managed to get it linked 
to the dynamic link loader, which may or may not be present as a static 
library on your system. You may have to supply the libld as an extra 
argument to your LDFLAGS. Do this by trying

	$ LDFLAGS=-ldl make nrpe

Note that this is just a wild guess. The solution should be somewhere 
along that line though.
