[Icecast] two problems with flac and ices 0.4 build

[Darrell Berry]

i'm trying to build ices0.4 and vorbis-tools 1.0.1 with flac 1.1.1. 
Neither seems happy, hence the crossposting (sorry).

ICES0.4

ices refuses to see the libFLAC library, even if i specify 
--with-flac=/usr/local/lib (or even just --with-flac=/usr/local/, as the 
configure script seems to look in the lib and include subdirectories of 
the specified path?). i get a configure error:

configure: error: Could not find libFLAC

(can provide trace of ./configure if that would help anyone). FWIW, 
/usr/local/include contains (amongst other things):

FLAC, FLAC++ and OggFLAC

and /usr/local/lib includes

/usr/local/lib/libFLAC.a           /usr/local/lib/libOggFLAC.a
/usr/local/lib/libFLAC++.a         /usr/local/lib/libOggFLAC++.a
/usr/local/lib/libFLAC.la          /usr/local/lib/libOggFLAC.la
/usr/local/lib/libFLAC++.la        /usr/local/lib/libOggFLAC++.la
/usr/local/lib/libFLAC.so          /usr/local/lib/libOggFLAC.so
/usr/local/lib/libFLAC++.so        /usr/local/lib/libOggFLAC++.so
/usr/local/lib/libFLAC++.so.4      /usr/local/lib/libOggFLAC++.so.0
/usr/local/lib/libFLAC++.so.4.0.1  /usr/local/lib/libOggFLAC++.so.0.1.1
/usr/local/lib/libFLAC.so.6        /usr/local/lib/libOggFLAC.so.1
/usr/local/lib/libFLAC.so.6.0.1    /usr/local/lib/libOggFLAC.so.1.1.1

All help appreciated
