Compile ffmpeg with librtmp

When compiling ffmpeg for OSX, I can simply use the:

./configure --enable-librtmp --enable-gpl

command and get a build that can I/O with an rtmp stream.

If I attempt to compile for iOS using: 

./configure \
--disable-ffmpeg \
--disable-ffplay \
--disable-ffprobe \
--disable-ffserver \
--disable-mmx \
--enable-gpl \
--enable-shared \
--enable-librtmp \
--enable-avresample \
--enable-cross-compile \
--enable-pic \
--sysroot="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs /iPhoneOS6.1.sdk" \
--target-os=darwin \
--cc="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/llvm-gcc-4.2" \
--extra-cflags="-arch armv7s -mfpu=neon -miphoneos-version-min=6.1" \
--extra-ldflags="-arch armv7s -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk -miphoneos-version-min=6.1" \
--arch=arm \
--cpu=cortex-a9 \
--prefix=compiled/armv7s

it errors out saying ERROR: librtmp cannot be found. Specifically: 

    /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/llvm-gcc-4.2 -arch armv7s -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk -miphoneos-version-min=6.1 --sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk -Wl,-dynamic,-search_paths_first -I/usr/local/include -L/usr/local/lib -o /var/folders/4m/8hcrycqx777_ksz6d32nrn_m0000gp/T//ffconf.b2zp97z8 /var/folders/4m/8hcrycqx777_ksz6d32nrn_m0000gp/T//ffconf.VhdlpSe1.o -lrtmp -lz -lssl -lcrypto -lm -lbz2 -lz

I have already compiled openssl for ios using ios-openssl found on github and librtmp through rtmpdump

I ended up compiling librtmp and openssl using ios-librtmp and ios-openssl, installed rtmpdump and openssl using brew, export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig, and then changing the files in /usr/local/lib/pkgconfig for libcrypto.pc, libssl.pc, openssl.pc, and librtmp.pc to point to the iOS i386, armv7 & armv7s compiled libraries.
