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)
libssl.so.5 => /lib/libssl.so.5 (0x009b3000)
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)
libcrypt.so.1 => /lib/libcrypt.so.1 (0x009f7000)
libresolv.so.2 => /lib/libresolv.so.2 (0x0014e000)
libnsl.so.1 => /lib/libnsl.so.1 (0x00a62000)
libdl.so.2 => /lib/libdl.so.2 (0x00c4f000)
libm.so.6 => /lib/libm.so.6 (0x00c29000)
libc.so.6 => /lib/libc.so.6 (0x00afd000)
libcom_err.so.2 => /lib/libcom_err.so.2 (0x0038e000)
libgssapi_krb5.so.2 => /usr/lib/libgssapi_krb5.so.2 (0x0099a000)
libk5crypto.so.3 => /usr/lib/libk5crypto.so.3 (0x00483000)
/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.
