Seems as though the guile I have from the FC2-x86_64 installation was not compiled gnu readline support. Does anyone know why? % ldd `which guile` libguile.so.12 => /usr/lib64/libguile.so.12 (0x00000030bfe00000) libguile-ltdl.so.1 => /usr/lib64/libguile-ltdl.so.1 (0x00000030c0000000) libdl.so.2 => /lib64/libdl.so.2 (0x00000030bd900000) libcrypt.so.1 => /lib64/libcrypt.so.1 (0x00000030c3300000) libm.so.6 => /lib64/tls/libm.so.6 (0x00000030bde00000) libc.so.6 => /lib64/tls/libc.so.6 (0x00000030bdb00000) /lib64/ld-linux-x86-64.so.2 => /lib64/ld-linux-x86-64.so.2 (0x00000030bd 700000) % rpm -q guile guile-1.6.4-11 Thanks, Nathaniel
