Can't Compile (Score 1)

Hello, I can't wait to watch my karma drop to bad after posting this because it's off topic or something... but I have tried all day to compile this downloading dozens of libraries... I'm stumped at this: checking how to run the C preprocessor... gcc -E checking for flex... no checking for lex... no checking for flex... ${SHELL} /home/dczx/TMR/ardour-0.9beta1/libs/gtkmm/missing --run flex checking for yywrap in -lfl... no checking for yywrap in -ll... no checking lex output file root... configure: error: cannot find output from ${SHELL} /home/dczx/TMR/ardour-0.9beta1/libs/gtkmm/missing --run flex; giving up configure: error: /bin/sh './configure' failed for gtkmm configure: error: /bin/sh './configure' failed for libs [root@localhost ardour-0.9beta1]# since there's no support forum I could find, does anyone have any ideas? thanks
