glad you've done a revision for this script to account for xcode 4.3. i'm having trouble compiling, however. i'm far from competent when it comes to this, but quickly looking over the script, i have a feeling it might be something to do with "LIBLEPT_HEADERSDIR=$GLOBAL_OUTDIR/include/" at line 39. again, i'm no pro here, but i can't see where it is declared and the build error is "leptonica not found" so given that this is the parameter for the leptonica path, i assumed there may be an association. any help appreciated! thank you
