Also, I decided to try this out for Ubuntu (since it's early in their 
development cycle) and it didn't go well:

https://launchpadlibrarian.net/174540862/buildlog_ubuntu-utopic-i386.clamav_0.98.1%2Bdfsg-6_FAILEDTOBUILD.txt.gz

Ubuntu doesn't use --as-needed, so it appears we're somewhat under linked at 
the moment:

../libclamav/.libs/libclamav.so: undefined reference to `setupterm'
../libclamav/.libs/libclamav.so: undefined reference to `tigetnum'
../libclamav/.libs/libclamav.so: undefined reference to `set_curterm'
../libclamav/.libs/libclamav.so: undefined reference to `del_curterm'
collect2: error: ld returned 1 exit status
