Error compiling gnuradio trunk

I am trying to install gnuradio from trunk to a
“Red Hat Enterprise Linux WS release 5 (Tikanga)”

Bootstrap gives the following error: error: possibly undefined macro: AC_PROG_MKDIR_P
If this token and others are legitimate, please use
See the Autoconf documentation.

Then configure executes with the following error messages

caen-vnc04% ./myconf > foo.log
./configure: line 5091: AC_PROG_MKDIR_P: command not found
pgf77-Error-Unknown switch: -print-search-dirs
configure: WARNING: If you wanted to set the --build type, don’t use
If a cross compiler is detected then cross compile mode will be

and the attached output.

Finally, make stops with the following message:

make[4]: Entering directory
/afs/' html make[4]: html: Command not found make[4]: *** [prep] Error 127 make[4]: Leaving directory/afs/’
make[3]: *** [all-recursive] Error 1
make[3]: Leaving directory
/afs/' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory/afs/’
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory
make: *** [all] Error 2

I don’t know why “html” is needed or what it is, but apparently cannot
be found.

Any ideas?
