I did build curl on the machine first and supplied the "--with-curl=/path/to/curl-config" since I am building to an user local directory.

I am providing the corresponding output below.</div><div id="yui_3_16_0_ym18_1_1458426789548_4586" dir="ltr"><br></div><div id="yui_3_16_0_ym18_1_1458426789548_5071" dir="ltr">...</div><div id="yui_3_16_0_ym18_1_1458426789548_4629" dir="ltr">checking for curl_global_init in -lcurl... yes</div><div id="yui_3_16_0_ym18_1_1458426789548_4636" dir="ltr">...</div><div id="yui_3_16_0_ym18_1_1458426789548_4660" dir="ltr"> cURL support (wms/wcs/...):yes<br>...</div><div id="yui_3_16_0_ym18_1_1458426789548_4686" dir="ltr"><br></div><div id="yui_3_16_0_ym18_1_1458426789548_4727" dir="ltr">when ii try running "gdalinfo /vsicurl/http:/path/to/image.tif" i get the following error</div><div id="yui_3_16_0_ym18_1_1458426789548_4769" dir="ltr"><br></div><div id="yui_3_16_0_ym18_1_1458426789548_4776" dir="ltr">./path/to/gdalinfo /vsicurl/http://path/to/ftype.tif<br>gdalinfo failed - unable to open '/vsicurl/https://s3.amazonaws.com/timmons-test/ftype_a_UT_projected.tif'.</div><div id="yui_3_16_0_ym18_1_1458426789548_4840" dir="ltr"><br></div><div id="yui_3_16_0_ym18_1_1458426789548_4841" dir="ltr">./path/to/gdalinfo --debug on /vsicurl/http://path/to/ftype.tif<br>gdalinfo failed - unable to open '/vsicurl/https://s3.amazonaws.com/timmons-test/ftype_a_UT_projected.tif'.</div><div id="yui_3_16_0_ym18_1_1458426789548_4856" dir="ltr"><br></div><div id="yui_3_16_0_ym18_1_1458426789548_4843" dir="ltr">./path/to/gdalinfo --debug on --config CPL_CURL_VERRBOSE YES /vsicurl/http://path/to/ftype.tif<br>gdalinfo failed - unable to open '/vsicurl/https://s3.amazonaws.com/timmons-test/ftype_a_UT_projected.tif'.</div><div id="yui_3_16_0_ym18_1_1458426789548_4844" dir="ltr"><br></div><div id="yui_3_16_0_ym18_1_1458426789548_4855" dir="ltr">gdalinfo works just fine when the tif is local.
