Why?
I'm not sure what the default build instructions are, but i've got
the following on my linux box...
granicus:~% ldd /usr/bin/postgres
linux-gate.so.1 => (0x00368000)
libpam.so.0 => /lib/libpam.so.0 (0x00311000)

libcrypto.so.5 => /lib/libcrypto.so.5 (0x00507000)
libkrb5.so.3 => /usr/lib/libkrb5.so.3 (0x003ab000)
libz.so.1 => /usr/lib/libz.so.1 (0x00c55000)
libreadline.so.5 => /usr/lib/libreadline.so.5 (0x00c6a000)
libtermcap.so.2 => /lib/libtermcap.so.2 (0x00dfa000)

/lib/ld-linux.so.2 (0x00adf000)
libkrb5support.so.0 => /usr/lib/libkrb5support.so.0 (0x0041f000)
Quite a list. I wonder what readline is doing there.
It would appear that linking against libraries is just fine, I don't
see that uuid is any different.

Not sure what uuid library you were using, but the one i used
is not LGPL. I posted earlier the copyright and license portion of
the readme. No relicensing would be necessary.
